Supergirl's Melissa Benoist & Jenna Dewan Visit 'Grease Live' Set in Full Costume!

Melissa Benoist and Jenna Dewan-Tatum pose for a photo with Julianne Hough in their full Supergirl costumes while visiting the set of Grease Live on Friday night (January 29) at Warner Bros. Studios in Burbank, Calif.

The ladies joined the audience to watch the final scene of the dress rehearsal, which was “You’re the One That I Want” on the carnival set. They were joined by their show’s co-creator Ali Adler and they also met up with Didi Conn, one of the original Grease stars. See photos of them trying on the Pink Ladies jacket in the gallery!

We’re guessing this brought back memories for Melissa as she performed the song on Glee alongside her now-husband Blake Jenner. Watch that clip below.

There were a bunch of stars in the crowd at the event, which was the first run-through of the show with a live audience in attendance. In Julianne‘s cheering section were her fiance Brooks Laich, their mutual friend Teddy Sears, Aaron Paul and his wife Lauren, and hair stylist Riawna Capri.

Vanessa Hudgens‘ boyfriend Austin Butler was seen hanging out with pal Oliver Trevena while Aaron Tveit had support from his former Graceland co-stars Vanessa Ferlito and Manny Montana.

Former Dancing With the Stars contestant Brant Daugherty was at the rehearsal to support his friend Elle McLemore, who plays the role of Patty Simcox.

Make sure to watch the live production on Fox on Sunday night (January 31) at 7/6c.
