On Wednesday night, Astronaut will compete against Night Angel, Rhino and T-Rex to make it into the Super Nine

Meet them at the mall, it’s going down.

In PEOPLE’s exclusive preview of Wednesday’s episode of The Masked Singer, Astronaut offers up a LEGO clue to panelist Nicole Scherzinger to help them her identity the celeb under the out-of-this-world costume. The clue: a LEGO mall with Minifigures of Astronaut and the Pussycat Dolls singer, 41. (LEGO Masters host Will Arnett serves as a guest judge.)

“Remember when we were both together to celebrate a huge birthday?” Astronaut asked Scherzinger.

After cracking up over her LEGO Minifigure’s appearance, which features a short dark bob and a sparkly top, the pop star said, “No, I don’t! I don’t remember!”

Last week, Swan missed out on her chance to advance when she got the boot and was unmasked as singer and actress Bella Thorne. The 22-year-old said that performing undercover on the Fox singing competition helped suppress some of her stage freight.

“Usually when I performed in the past — I’ve performed at Billboard and a few really big festivals and whatnot — and right after I’m done I get off stage and I have to throw up because I’m so nervous that I feel it coming while I’m on stage,” Thorne told PEOPLE.” ’Im literally so nervous. On The Masked Singer I didn’t [throw up], not once and I think it was because the Swan mask made it so I didn’t feel as nervous.”

The Masked Singer airs Wednesdays (8 p.m. ET) on Fox.
