If you haven't gotten over learning that former vice presidential candidate Sarah Palin was under the Bear costume last week singing "Baby Got Back" on The Masked Singer, you're not alone.

"We're still recovering from last week and the most shocking reveal in Masked Singer history after Sarah Palin, also known as the Bear, left us all speechless," host Nick Cannon said at the beginning of Wednesday's episode.

The remaining Group C contestants - Astronaut, Swan, T-Rex, Night Angel and Rhino - returned for their second performance of the season, and guest judge Joel McHale joined panelists Jenny McCarthy, Ken Jeong, Nicole Scherzinger and Robin Thicke. As part of this season's Masked Academy theme, Cannon asked each contestant to offer up a yearbook quote after their performance as an additional hint.

The judges thought Rhino's version of "Nice to Meet Ya" by Niall Horan would certainly secure him a spot in the Super 9, and the studio audience's vote confirmed that when they selected their favorite performance at the end of the night. The vote left Swan - who had professed her love for Jeong after singing "I Hate Myself for Loving You" - at the bottom, which meant she would have to unmask.

The panelists' final guesses consisted of a range of actresses including Nina Dobrev, Megan Fox, Olivia Munn, Mila Kunis and Kristen Stewart, but when the crane came off, Bella Thorne turned out to be under the feathery costume.

"Well because Ken was guessing me as the Flamingo last season and I retweeted that and that made me super excited and I just started watching the show and I thought it was so, so amazing, so dope and I was like, 'Let's do that!' " the 22-year-old singer and actress said of why she wanted to do the show. "Getting in front of people really gets me super nervous, so this was really out of my comfort zone."

Jeong kicked himself for not suggesting Thorne because they appeared together in rom-com The Duff.
