On Tuesday, September 28 at the Frankie Jonas' 10th birthday party, Joe was seen accompanied by his rumored girlfriend Ashley Greene.
Joe Jonas has fueled rumors he is dating "Twilight" beauty Ashley Greene after they were snapped walking arm-in-arm through Beverly Hills, California. The pair prompted speculation of a romance after they were spotted enjoying a meal together in London over the summer.
And the Jonas Brothers star did little to dampen gossip about his relationship with the actress when they were seen embracing as they walked to his younger brother Frankie Jonas' 10th birthday party on Tuesday, September 28.
Greene is the latest young star to be linked to the singer - he has previously dated Taylor Swift and Demi Lovato. He was also once romantically linked to Camilla Belle.
"Happy birthday Frank! Fun basketball birthday party! Love you big guy!" he tweeted. "Called frankie 10 times this morning to realize he was in school. Hope his phone wasn't taken away!!"
