John Mayer & Jessica Simpson Back Together Already?

Jessica Simpson and John Mayer reunited in New York City on Sunday night, sources close to the situation tell PEOPLE.

"They definitely went on a date last night. She still loves him... but he's scared of commitment. He breaks up with her and then regrets it and then begs her to get back together."

"They're in a normal relationship," says the source. "This happens with relationships sometimes."

Adds the source: "They went on a date last night. They had a great time. They had dinner."

Jessica Simpson and John Mayer Split

Jessica Simpson and John Mayer have ended their romance – but perhaps not for good, a source close to Simpson tells PEOPLE.

"They have broken up," says the source. "But they have broken up and gotten back together at least ten times before."

According to the source, the pair are in constant contact – even as Simpson promotes her film Major Movie Star at the Cannes Film Festival in France. "They talk to each other at least six times a day. I don't know if this breakup is permanent, but for right now they are broken up."

In fact, the pair have "been emailing and talking to each other," since Simpson went to Cannes, says a Simpson friend. "I'm sure they'll get back together."

Daddy Simpson Approves of Jessica's Lover John Mayer

Jessica Simpson has been dating John Mayer since last August and has won her father Joe’s approval with her latest relationship.

Joe told People magazine: "If Jessica is in love, I love the things she is in love with. I want her to be happy. I’m always a fan of John. I love him - he’s got great music." Jessica’s father hasn’t always approved of her previous lovers. He warned his daughter marrying Nick Lachey could ruin her career.

Jessica, whose divorce from former 98 Degrees singer Nick was finalised last June, said: "Everybody thought, including my father, that my marriage to Nick would kill my career."

Joe is convinced Jessica will be happier with John because they have a different fan base and are equally famous.

He explained: "I think the beautiful thing is that he and Jessica don’t do the same thing. He’s a legend already. There is no competition. He’s a guitarist - that’s his thing. Jessica is a singer. She doesn’t play guitar, so there’s no competition." Jessica joined John on tour in Australia last month, and is currently in France attending the Cannes Film Festival.
