Well isn’t that interesting yet predictable. Just a day after it came out that Joe Jonas, 21, enthused to Details about how well his relationship with Ashley Greene is working out, because she “really puts my feelings first,” we hear that the two are kaput. Greene, 24, seems like a real social climber and I would bet that she was the one who did the dumping. Still, The NY Post claims it was mutual, which is publicist speak for “don’t speculate.”

“Twilight” beauty Ashley Greene and “heartbreaker” Joe Jonas have split, sources exclusively tell Page Six. The couple broke up weeks ago after dating since last summer. “It was mutual and amicable,” a source said, adding they drifted apart because of their work schedules. The Jonas Brothers star gushed about her in Details’ April issue: “I think what works about it is she really puts my feelings first. She understands my busy schedule.” Greene is filming “The Twilight Saga: Breaking Dawn” and will appear in “LOL” with Demi Moore and “Butter” with Jennifer Garner this year. Jonas is to release his first solo album this summer. He previously dated Taylor Swift and Camilla Belle and split with Demi Lovato, earning himself a reputation as a heartbreaker. Greene didn’t seem to be nursing too much of a broken heart when she hung out at Avenue Tuesday night with friends including Jared Followill. A rep for Greene couldn’t be reached. A rep for Jonas declined to comment.

“Weeks ago” means less than three weeks in their case as I was able to find photos of them together on 2/24/11, which is when the photo above was taken. They’d been together almost a year, which is ages when you’re in your early 20s, so it might just have been time for them. If this is true I suspect that Ashley realized that Joe’s star was on the wane and that it was time to move on to someone who would help raise her profile. I predict she’ll be seen out with random actors we’ve vaguely heard of until she lands one that sounds more familiar and stages pap walks with him every week. And in the mean time there will probably be an announcement in People framed to make her sound like a survivor with a promising career. Joe’s people won’t get on this as soon as hers will, because he’s probably hoping it’s not final.

Update: This is now in People, and both reps confirm it’s true that these two have broken up. The story isn’t as pro-Ashley as I was expecting, although I still think she dumped him.
