Anne Hathaway geeks out over Mariah Carey at movie premiere

NEW YORK (AP) -- Anne Hathaway may be an Oscar winner, but when it comes to Mariah Carey she's a total fan girl.

The singer attended the premiere of Hathaway's new movie "The Intern" with Robert De Niro this week, and her presence made the actress lose her cool.

"She's here. She's at MY movie premiere," gushed Hathaway on Monday's red carpet.

When a reporter told her Carey was spotted getting her hair brushed off to the side before stepping out on the carpet, Hathaway couldn't put together a sentence.

"That's just the best glamorous ever. That's not even a sentence. There's no grammar there. The best glamorous ever, yeah. I went to college. I didn't graduate," she laughed.

Hathaway tried to focus on questions about her film but was clearly distracted by her proximity to Carey.

"She's now an arm's length away," she said, "I love that you're getting this on camera."

In "The Intern," opening Friday, De Niro plays a bored widower who gets accepted into an internship program for senior citizens at an e-commerce company, run by Hathaway's character. The two end up bonding and learning from each other.
