Matt Cardle sings 'Unfaithful' with Rihanna - The X Factor Live Final - (Full Version) 

His voice is so emotional for this duet performance

GODD HER VOICE IS INCREDIBLE THIS WOMEN IS SOOOOOO TALENTED SHE SOOO BEAUTIFUL SHE HAS AN AMAZING VOICE SHE IS SICK DANCER I DONT NO WHAT TO SAY SHE'S PERFECT

I cant Remember him doing it this bad, but Love Rhianna

Took me a while to realize it was Matt who hit that super high note at the end. They sound amazing together! xxx

this is like one of her best live preformance

Matt has 3 self-written post-xfactor solo albums out by now. Check them out :) "Letters" (2011), "The Fire" (2012) and "Porcelain" (2013). 4th album coming soon!

I love seeing success stories like Matt's. Too many youngsters these days blame society, parents, schools and everyone but themselves for their troubled lives and very few of them rise above their circumstances. Matt didn't even play the pity card but instead worked hard to make this a success. You're a star matt and I hope you keep making your father proud.

I can't stop watching Matt Cardle, I do have his Letters cd and I listen to it a lot but I keep going back to the X Factor. good on you Matt. Brian upton

One of the best duets on the X Factor, ever!

Oh for god sake he nailed it!! Imagine a regular builder from the uk he's singing and realisation about to kicks in Rihanna a worldwide superstar is about to walk on stage and duet with him!! That would be enough to make my voice disappear totally!!!!

his voice can touch people's heart. he may not be the best singer but he's what most singers lack these days.

I know is from 2010 but I still looking at...ty

You're the man tonight Matt!

I really love matt, hes simply amazing

He is just so so amazing. A truely nice guy with the voice of an angel

Oh my God what he should be proud of him self now!! Go Matt!!!

I think this duet made him win, it was amazing

two years on and this is still amazing:o

when i watched this on tv i was screaming snoggg i believed every word they were singin it was amazing xxx

whenever someone says she cant sing i direct them to this video cus its absolute proof she is amazing

Goosebumps Goosebumps So Many Goosebumps!!

the chemistry is hoooot!

that was stunning

Yooooo that was awesome!!!!!!

I can't believe finalist's videos of the 2010 UK show get so many dislikes, nearly all of them were perfect. trust me, if you saw X-factor 2011 Hungary, you would really appreciate these amazing singers.

rihanna is absolutly stunning! amazing voice and beautiful girl love her

brings back so many good memories from x factor 2010...alot sexual tension in this performance from both of them...best duet on the x factor!

I love this so much omg

I loveeeeeeee mattt !!!!!!!!!!!!!!!!!!!!!!!

hes very adorable in this!

Amazing!!! love this video

This is amazing!

love amtt all the songs he sang were brill can sing anything

Would love to see these two do another duet sometime. :).

Fair play. This is probably the highlight of his life right here. He will never perform with as big a name as her again.

Amazing rihanna great voice

He sure is just about to release his third album. Sings like an angel!!

I love you Rihanna

He is on his way, carrying that beautiful voice.

Lets also keep in mind that while singing this Matt had a bad throat infection, and imo he still fckn OWNED this song! He's an amazing singer, theres too many tweenie boppers like 1D out and not enough raw talent like this.

Oh my gosh Rihanna is so beautiful

His voice became much stronger after he started singing with her. I love the harmony--Rihanna's naturally low voice&his high voice blended well together.

Love it!!

I SHIP THEM

he was so emotional .. i thought he was about to cry !

She rocks.

Omgg they should go out..I think they would make a cute couple.

Good perform as awlays !!! Beautiful as always !!! Perfect as always !!! It's RIHANNA !!!!! Who else ??

No im laughing at that other guy thinking it was Patrick Dempey hahaha!! Glad you put him right ;)

aww gotta love this though, i love mat!!!! i always knew he would win

Yea it doesnt change the fact Rihanna has sold nearly 200mil albums and singles worldwide, so clearly the biggest artist he will ever perform live with and the biggest moment of his career

woow.. they are a good couple like singing together on stage :) i like this version of Unfaithful ^^ GO MATT GO GO MATT

hehehehe ... i love matt cardle and every time i watch this video i giggle becuz of the looks he is giving her when they are singing....he is soaking in the moment and looking to that leg popping out of the dress............. lol ...........so cute! and so typical of a guy meeting his idol.

Can't not think about when I saw him live in the 2nd row

...He reminds her of a place where she once sung from...a place in mind...in time....lost & blinded away...

matt cardle is amazing :)

3.13 ooohh lala matt's getting all excited! Great together

might as well go out LOVE YOU MATT

Briliant! Nothing more to say.

Holy lord, she's so damn gorgeous!!!

for some reason i cant stop smiling when she came out. :D i guess i felt for him.

his cheeky little face watching her leg. and he didnt even mean to go that high at the end;) he just got a bit excited!

your boy did that!

OMGG RIHANA!

where are all the fire'ers the stage went up! cant blame ya Matt! she's HOT ....

They so wanted each other!!!!

i luved it...xxx

Wow! They did NOT need those artificial flames in front of the stage. With the chemistry between those two, they could burn up the stage all on their own. Terrific!

I ♥♥♥ You Rihanna so much ..!! matt you are so lucky you actually sing with Rihanna

I wonder how he can sing, if I were in his place would have fainted! rihanna

this was a very nice duet.

they should go out :)

OMG! Matt is so adorable, at 2:30 he is like a little nervous guy at his first date :D cutie :)

un cantante admirable. su exito de el esta en su sensilles

I was like DONT YOU DARE KISS HER MATT!! haha

Yassssssssss matt won

amazing duet. rihanna was perfect for this, and the song was too. Love it!!

He dosnt need too to be honest. He has a fantastic talent and is brilliant live.

i loved this song when rihanna did it but it sounds amazing when matt sang it with her

FUCKK OMGG RIHANNA VOICE IS FUCKING AMAZEING HER VOCALS MADE ME CRY.

At the end, Matt whispers, 'Sorry about the poke in your stomach' lol

Most XFactor finalists sound quite rubbish when they duet with the stars but he still sounds amazing. ♥

Bravo!!!!!!!!!

4:31 : HER LAUGH !!! DAMN I REALLY LOVE IT !!!! GOD I LOVE THAT GIRL !!!

this is " star crossed lover's syndrome" the chemistry between these two is mind blowin, n i hope it's coming my way xxx

Matts probably thinking, hang about we didnt do this in rehearsals!! lol

Matt bit his finger looking at knicker-less Rihanna! Go Matt!

he has still got a bad throat and he sings like this??!!! :-O he is amaaazing!! i would buy his album and listen to it all day!! go matt!!MATT 2 WIN!! loved his first time ever i saw your face version!! aaand baby hit me one more time! :-D x

I really enjoyed this and at 4:29 he's really enjoying looking at her leg..lol. Rihanna was a sweetheart and I think the both did well.

Ficou muuuito perfeito!

To everyone saying Matt sang badly, newsflash: he was ill and did his very best. And AND HE WON! Suck on that.

Awesome channel ♥ ♥ ♥

@ysislore he's still sicker than a dog, but you notice he isn't complaining, weeping or wailing; he's doing the best he can which is still fantastic - Matt to win!

wonderful

Rihanna is just an amazing woman. She makes EVERY SINGLE guy look like a young boy, even drake said that she made him feel NERVOUS. She has this confident sexappeal,she's just BEAUTIFUL. And she gets better and better with her performances!

He is amazing, He had a sore throat and still got up there and sang, when i had a sore throat and had to sing in drama, I just skipped out cos I couldn't hit the notes right!

He's one lucky lucky lucky man.

i loved it when she first stepped out and her expression was like "yes i'm fckin hot..watch me do da damn thang"

@SWndLOVINGYOU Cuz Matt has an unusual beautifull voice... Even high notes aren't a problem for him... I love his songs.

TBH, it only gets good when Rihanna comes on and the fire goes on
