Justin Bieber need's mom's dating approval

Justin Bieber's mother has to approve his girlfriends.

The singer - who is dating 18-year-old Disney star Selena Gomez - wouldn't want to enter a relationship with a "bad girl" because he knows his mom Pattie Mallette wouldn't welcome her into their home.

He said: "I wouldn't bring home a girl unless my mom would approve. You don't bring the bad girls home to mom."

The 'Justin Bieber: Never Say Never' star - who celebrated his 17th birthday yesterday (01.03.11) - also admitted he has no preference about the age of the girls he dates.

Asked if he likes older women, he said in an interview with Sirius XM radio station: "I'm into women in general."

Justin also spoke about his influences and inspirations, insisting there is no one star whose career he wants to mimic.

He added: "I don't think I want to emulate anyone's career. But just take different bits and pieces from different people. Definitely Michael Jackson, and lately I've been really studying Fred Astaire."
