From one girl to another. From Jessica Simpson to Mandy Moore, John Mayer at last gives his heart to Cameron Diaz. The singer who has just created media headlines with his being photographed enjoying an intimate lunch with longtime friend Moore in Soho on Tuesday August 14th is now reported to be dating movie siren Diaz.

Diaz and Mayer were spotted out and about in New York on Tuesday night August 14th. "They went out to several places...It was the two of them, getting to know each other, out on the town," a source in the know told Us Weekly while went on saying, "This was technically not their first time hanging out...they've hung out together with friends before. But this was the first time together like this. It's new and developing...but they really like each other and it went well."

A representative for Mayer refused to comment on that matter though, claimed "We do not comment on our client's personal lives." Diaz' s camp, meanwhile, also remained tight-lipped.

Moore, elsewhere, has on early Wednesday August 15th put to rest rumors that she and Mayer are dating, telling reporters "Oh my goodness. John and I have been friends for years, no romance."
