Justin Bieber asked mommy if he could stay the night at Selena Gomez's house for a pajama party

After a late night having dinner at Mastro's restaurant in Beverly Hills, Selena Gomez suggested to her squeeze Justin Bieber that he stay over for a pajama party.
Being the good son that he is, Justin had to whip out his cell phone in the limo and call his mommy to get the OK to stay over.

As soon as he got off the phone, he turned to Selena and said excitedly, "Mom said it was okay!"
LOLz! We're actually kinda surprised she did say okay, considering Justin is only 17. But we're sure it was all just innocent fun, right? Right???
