Has Christina Aguilera Already Moved On?

Has Christina Aguilera (who divorced Jordan Bratman just three weeks ago) already moved on with a production assistant from her new movie, Burlesque?

A source close to the couple told People.com that Xtina and Matthew D. Rutler are dating, and that what started out as an innocent friendship has turned into something romantic.

“It’s not serious yet, but it’s something she is exploring and finding comfort in,” the source dished. “It’s new and she’s taking it day by day."

Over the weekend, Christina and Matthew were photographed on a double date with Nicole Richie and her fiancé, Joel Madden at the SoHo House in West Hollywood.

Another source told E! that Christina and Matthew were very affectionate with each other at the club.

"The group was hanging out in a corner of the private club together. Christina and Matt were cuddling on a couch together and left holding hands,” said the eyewitness. “They definitely seemed like a couple."

But Matthew’s mother, Kathleen Rutler, is denying reports that her son and the Ecuadorian singer are a couple, telling Perez Hilton that the couple are “absolutely not dating,” and are “just friends.”

“There is no doubt he enjoys Christina’s company, as a friend!’ explains Kathleen.  “That is what she wants right now, a friend.”

Kathleen adds that her son told her, "Christina needs a shoulder to cry on and an ear to listen to her problems."
