The rumours seem to be true: Cameron Diaz and Benji Madden are dating.
Diaz, 41, was spotted kissing Madden, 35, while having breakfast in New York City.
Rumours that the pair were more than acquaintances began circulating after they were photographed together at a Los Angeles gym.
Word is that Nicole Ritchie, Madden's sister-in-law, set them up. But when Sydney radio station Kiis 1065 quizzed the Good Charlotte rocker on air, he was reluctant to talk about his private life.
Australian Shock jock Kyle Sandilands asked: "Apparently, Nicole's been matching you up with Cameron Diaz, what's happening there?"
Madden said: "Oh Kyle and Jackie O, you know what, I'll talk about it when I see you next week."
In response to the gym photos, Madden said: "I love the gym, I do a lot of curls."
While Madden kept mum on his status to the radio jocks, there was no hiding his feelings in photos that emerged over the weekend.
An eye-witness spotted Diaz and Madden having breakfast at Manhattan's ABC Kitchen.
"Throughout the entire meal, Cameron and Benji couldn't keep their hands off each other," the source told The Star.
"They were whispering to each other and laughing, just having the best time together."
Despite being out with a group of six people, The Star reported that they appeared to be in a world of their own.
"Benji kept his arm around her, and she'd just rest her head on his shoulder and stare at him, grinning. It was obvious that she's crazy about him."
But according to a 2010 interview, Diaz, who has previously dated Justin Timberlake, Jared Leto and baseball player Alex Rodriguez, doesn't believe in monogamy.
The blond bombshell said: "Relationships can last two, five or 20 years. I don't believe in sharing your bed with the same person your whole life, though. That might be a reality for some, but it surely isn't for me."
But The Other Woman actress has said she does believe in soul mates.
"There are many soul mates. My soul has a lot of different facets and it needs a lot of different men," Diaz told Us Weekly.
"Friends, too. Friends can be soul mates!"
Monogamy or not, a source close Diaz told People magazine that she's at a point in her life when she would love to settle down.
"But for now with Benji it's about being happy and taking things as they come," says the source.
"I wouldn't be surprised if they are together for a very, very long time."
"She's happy ... really happy."
