Jared Followill is dating Ashley Greene.

The Kings Of Leon rocker has reportedly called off his engagement to 23-year-old model Alisa Torres in order to start a relationship with the 'Twilight Saga: New Moon' actress.

A source told America's OK! magazine: "They were immediately attracted to each other the night they met at a Kings of Leon show in Vancouver.

"They kept in touch and finally he ended it with the fiancee to give it a try and now they're in New York together."

The new couple were spotted at New York nightspot The Box last week where they celebrated Jared's 23rd birthday by "holding hands and making out."

Ashley, 22, was most recently romantically linked to her 'Twilight' co-star Kellan Lutz.

However, the actor recently laughed off speculation they were dating, saying: "Every day I hear that Ashley and I are dating.

"It's like, why can't friends be friends with the opposite sex? Like, is it that bizarre?"

In August, Ashley's 'Twilight' c-stars Robert Pattinson and Kristen Stewart were spotted kissing while they watched a Kings of Leon concert, despite repeatedly insisting they are not having a relationship.
