The Jonas Brothers singer, 21, and Ashley Greene, 24, actually split up a few weeks ago after dating since Summer 2010. The couple broke up down to "conflicting work schedules", according to NYPost.
"It was mutual and amicable," an insider close to the pair explained, "They broke up shortly before her birthday, then got back together."
But in the recent interview with Details magazine, Joe gushed about Ashley in the April issue which was published this week: "I think what works about it with Ashley is she really puts my feelings first. She understands my busy schedule. She'll fly out to my shows - she's been to places in South America that I can't even pronounce."
Reps for both stars has confirmed the split.
The pair are both currently in NYC. Joe is working on his upcoming solo album. Ashley has been shooting a new campaign for cosmetics brand Mark.
