Remember the scene in Mean Girls when Damian—aka everyone's favorite "too gay to function" best friend—sang Christina Aguilera's "Beautiful" with Tina Fey accompanying on piano? It's one of the best high school movie scenes of the last decade, and apparently Christina Aguilera, of all people, hasn't seen it.

As millennials around the world celebrate the 10th anniversary of Mean Girls, Damian—real name Daniel Franzese—did an interview with Yahoo! Movies to share insider secrets about the teen flick. Turns out "Beautiful" won't be his go-to karaoke song.

"I met Christina Aguilera and I thought for sure that would be an exciting moment in my life," the New York-bred actor said. "I was like, 'Christina, my name's Daniel. I sing 'Beautiful' in Mean Girls. And she was like, 'Never saw it.' And then turned her back and walked away. She was so rude."

Aw, Xtina! If you're embarrassed about not seeing Mean Girls, we'll totally watch it with you at a slumber party. Call us. Or at least Mariah—it's her favorite movie!
