'SYTYCD' Week 10: Who Should Win?

The top four dancers on So You Think You Can Dance had the grueling task of performing five routines each this week. And it's now up to America to choose one guy and one girl as the Season 10 champs!

As is the case each season, the dancers were put to the test having to perform five times throughout the show. And yet the contestants delivered some crowd-pleasing numbers that also celebrated their respective journeys on the show.

Remarkably two sets of original season 10 partners-- Amy and Fik-Shun, Jasmine and Aaron-- have made it the finale. And while each have had a stellar run and has certainly earned a spot in the final four, there's one contestant host Cat Deeley hopes will take it all the way.

"I have an invested interest in [Jasmine]. I thought she wasn't going to be in the top 20 and I fought for her," she says. "I love the fact that America is seeing what I saw."

As for his overall impressions of last night's finale performances, Nigel agreed it was a decidedly tough night for them all.

"I think they have us 100% [but] it didn't always show them off to their best," he said.
