Mandy Moore the snob

Mandy Moore played the best snob she could to help out a new group.

The teen pop star appears in Good Charlotte's video for their debut single "Little Things," Allstar reports.

Mandy plays the part of a super-popular high school girl to the group's lead singer, Joel.

"She plays my hot ex-girlfriend who breaks up with me because I wasn't cool enough in high school," Joel told Allstar.

But Joel was quick to point out that Mandy's snobby act wasn't real.

"She was very down to earth and sweet -- everything you could say good, she was it," Joel said. "I honestly wasn't excited about meeting her, but when I met her, I totally dug her," he told Allstar. "She was really hot ... I want to ask her out on a date. Maybe in a year or so I may have to take her to Vegas and get married."
