Sasha Pieterse Will Be Sparkling on Tonight's 'DWTS' Premiere

Sasha Pieterse will make her debut on Dancing With The Stars tonight, with pro partner Gleb Savchenko, and there’s no missing her — because she’s in so many sparkles!

The Pretty Little Liars star teased fans about her costume with ET, saying, “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.”

She adds, “It’s something that I wouldn’t usually do, so all the costumes are incredible. The designers are amazing…every aspect has been amazing.”

Sasha also revealed that she’s definitely sore from all the practice so far.

“We’ve been having a lot of fun. I am sore and it’s really tough, but I’m loving it,” she says. “I expected it to be really hard.”

“Janel [Parrish] and Brant [Daugherty] were on the show and they loved it, but they told me it was really tough, so it’s been amazing and I’m as ready as I can be. But I really am just enjoying the process a lot.”

Dancing With The Stars premieres TONIGHT @ 8PM ET/PT on ABC.
