Yale’s own burgeoning celebrities Sam Tsui ’11 and Kurt Schneider ’10 were on “Ellen: The Ellen DeGeneres Show” Thursday.

“I’m in a winter wonderland, you’re here, it’s incredible,” Tsui said as the segment opened.

DeGeneres interviewed Tsui. The host gave a shout out to Tsui’s mom, who is a fan of hers, and pulled up baby photos of the singer.

The two Yalies performed a mash-up of Katy Perry’s “Firework” and Bruno Mars’ “Grenade.”
