“It’s a great song for the Cha-Cha… he did an amazing job choreographing it. There’s some sneak peeks or sneak surprises that are gonna be coming up when you see it, so it’s great,” Sasha revealed at EW’s Pre-Emmy bash at the Sunset Tower Hotel in Los Angeles on Friday.

The 21-year-old also promised lots of glitz!

“I rarely wear sparkles and, you know, ‘cause you see me all the time, so to be in so many sparkles, it’s actually a lot of fun. It’s something that I wouldn’t usually do, so all the costumes are incredible. The designers are amazing…every aspect has been amazing,” she shared before revealing that her fiancé, Hudson Sheaffer, is loving her glamorous ballroom transformation. 

“He loves it actually. He totally loves it. It’s a reason for me to get all dolled up and he can’t wait for the premiere, which is great,” she said.
