Darren and Lilia are married. So are James and Ola. I don't know who is gay. Anton and Erin are adnce partners. Ian dances with Camilla (but she's not in it this year), Flavia and Vincent, and Brian and Kristina.
Not sure who is gay it's hard to tell as they are all intouch with their feminine sides so much! Flavia and vincent were partners for 13 years until she danced with Matt de Angelo you could smell the sexual tension between those two and it was just meant to happen!
