Ashley Greene Joe JonasJoe Jonas appears to finally have met his match in Ashley Greene. The two have been an item since September and in the time since then, friends say Joe’s days of as a serial dater may be coming to the end.

“Even though Joe has had plenty of high-profile girlfriends in the past few years, he is impressed with Ashley’s joy of life and dedicated work ethic,” a source close to Jonas tells PopEater.

“They are both well grounded and have a basic understanding of who they are.”

Jonas; reputation as a lady’s man has always been marked by contradictions.

In 2008, he and his brothers, Nick Jonas and Kevin Jonas pledged to remain virgins until they wed, and the trio began wearing “purity rings” to remind them of their pledge.

The also become figureheads for a movement to convince other teens to avoid sex until they married. Miley Cyrus and Selena Gomez took a similar pledge.

Joe said at the time that he and his brothers made “promises to ourselves and to God that we’ll stay pure till marriage.”

At the same time, Joe had a succession of girlfriends. In 2006, he dated pop artist AJ Michalka, followed by Country queen, Taylor Swift.

Then he was seen with Camilla Belle, and before Greene, had a widely publicized fling with “Camp Rock” co-star Demi Lovato.

But Joe ditched his ring after hooking up with Greene. “When they’re not traveling they are basically living together,” a friend said.

The two had a lot of common.

Greene, the daughter of a U.S. Marine who attended Christian schools, likely shares the same outlook on life. She also understands the demands they both face because of their careers, according to the gossip Web site.

“We have already met each other’s parents,” she told the Teen Vogue, “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.”

But is Greene too good for Jonas?

She is drop dead gorgeous and her career is already eclipsing his, which has been the ruin of many a Hollywood relationship.

Only time will tell.
