Joe Jonas, Ashley Greene Break Up

Reps for the musician and 'Twilight' star confirm the split.

It's official. Joe Jonas and Ashley Greene are no longer a couple.

After rumors of their split hit the Internet early Thursday (March 17), the stars' reps confirmed the breakup to The couple began seeing each other last summer. A source told the website that Jonas was "head over heels" for the "Twilight" star at the beginning of their relationship.

The pair was regularly seen holding hands and getting cozy on dates, despite their two very busy schedules. He's currently working on a solo album after touring through much of last year with his brothers, Nick and Kevin, and she's busy filming "Breaking Dawn."

The news of the split comes one day after Jonas' interview with Details magazine, in which he gushed over the actress, hit the Web. "It feels good. I think what works about it is she really puts my feelings first. She understands my busy schedule," he told the magazine. "She'll fly out to my shows — she's been to places in South America that I can't even pronounce."

Earlier this year, Greene opened up to Teen Vogue about her then-beau, sharing some insights into what their relationship was like. "We met through mutual friends in London, which is crazy because we both live in L.A," she said. "And we've already met each other's parents, which I think is a good result of the kind of lifestyle we live. He's sweet and really funny, which is huge for me. We have a traveling relationship."

It seems though that all that traveling eventually made it hard for the pair to maintain their relationship. The New York Post reported that their busy work schedules contributed to the split, and that "it was mutual and amicable," according to a source.
