Nigel Lythgoe probably didn't intend to play matchmaker when he incorporated All-Stars into So You Think You Can Dance season eight, but that's exactly what happened for Allison Holker (of season two) and Stephen "tWitch" Boss (of season four), who are now engaged to be married!

The First Couple of So You Think You Can Dance recently swung by the ETonline offices to talk all about their seasons on the show. 

They revealed their favorite routines, most embarrassing moments, biggest jealousy inducing performances and the one piece they'd never like to dance again! 

So You Think You Can Dance airs Tuesdays at 8 p.m. on Fox and you can catch Holker on VH1's Hit The Floor, every Monday at 9 p.m.
