Maybe they were at the time .. but they married different people a few years later. And why would it matter? This is a routine - a show dance - and they are transporting the feeling of the song and their routine. With pro dancers: (almost) anything goes during competitions (mixed matched), flirting or sexy movements are no problem (no kissing ofc). And with shows it is just like actors. From personal experience I would never want my girlfriend to be my routine training partner - it can really really put stress on your relationship or badly impact your dancing if you do competitions and routines. And yes, my girlfriend knows my training partner and I know the boyfriend of my training partner. Either they accept our passion or they cannot be our girl/boyfriend. Just we respect their profession or hobbies. All in all: you dont OWN your partner... and loving means trusting.
