Jessica & John Make It Official

"They are dating,” a source close to John Mayer tells Us Weekly. “They're boyfriend and girlfriend. She flew into NY and stayed at his place."

On December 30, the couple enjoyed a late lunch of tacos and passion fruit margaritas at the Mexican eatery Dos Caminos in SoHo (“He paid and they held hands on the way out the door,” says a witness).

These pics were snapped while Jessica Simpson & John Mayer shopped at Barney's on 12.30. These spent New Year's Eve at The Hudson Hotel and partied the night away at club Stereo.

A rather odd pair, John shunning the spotlight like he does. I doubt he can handle her possessive father but he does seem the type to not take any shit. Something fun to watch in 2007.
