Cameron Diaz's Mayer lust

Cameron Diaz and John Mayer were "all over each other" in New York at the weekend.

The 'Shrek the Third' star and the singer - who were first seen together last week - were canoodling at the Bowery Hotel on Friday (17.08.07).

A witness told People magazine: "They were all over each other and super flirty. They sat on a couch in the back of the patio and were laughing and talking a lot."

When asked if the pair were dating, a source close to Mayer said: "Yes, it's definitely true."

The pair were first seen together having dinner at French-Vietnamese restaurant Indochine last Tuesday (14.08.07).

Diaz - who is in New York filming new romantic comedy 'What Happens in Vegas...' - split from her boyfriend

of four years Justin Timberlake in January.

Mayer, 29, split from on/off girlfriend Jessica Simpson in June.

Diaz, 34, was also seen dining-out with co-star Ashton Kutcher and three other men.
