During her interview, which aired Thursday night, Gomez, wearing a little maroon dress, opened up about growing up with a single mom. “She was a chameleon, my mom, because she was a single mom,” she said. “She basically raised me and had to work a lot of jobs. She did a lot of theater, though; she never did television. I loved watching my mom.”

Does her mom approve of beau Justin Bieber? “Yes [she met Justin]. He passed the test,” she said, giggling. Other hot topics included appearing on the covers of magazines, getting her driver’s license, getting into a fender bender and her love of fellow guest Jim Carrey’s movies.

Gomez was on the show to promote her new flick “Monte Carlo.” She’s also set to release an album this year. People reports that the singer’s appearance in Santa Monica on Friday has been canceled.
