FemaleFirst reported that Cameron Diaz is dating Jessica Simpson's ex John Mayer. The actress broke up with Justin Timberlake last January after four years together. She seems very cosy with musician Mayer, who dated Jessica Simpson on-off last year. Mayer and Diaz were seen together in New York last Tuesday. A source explained, "Cameron and John were strolling along the street hand-in-hand. They were nuzzling each other and looked besotted." The couple went to Indochine Restaurant on Lafayette Street for an intimate meal. "They were very playful and cosy. They drank cocktails and lingered over dessert." Diaz is in New York filming What Happens in Vegas. |
