Christina Aguilera in Playboy?

The irrepressible Mr. Hugh Hefner wants 6 week old mom Christina Aguilera to pose for Playboy.

"Hef has always loved Christina," an insider told OK! magazine. "He finds her Old Hollywood glamour stunning and magnetic."

While Christina, 27, is likely to be flattered by the offer it is unlikely she will take it, even though she is known for her wild past.

"That was old Christina. That was Christina circa four years ago. She's looking to reinvent herself and grow. She wouldn't consider it but she finds it to be flattering to be offered at all," says a friend.

Besides, her husband, record executive Jordan Bratman, may not be amused with the idea.
