MILEY CYRUS, JUSTIN GASTON SPLIT

CelebNews@Usmagazine.com! - Source: Miley Cyrus, Justin Gaston SplitAfter less than a year of dating, Miley Cyrus and Justin Gaston have called it quits, Usmagazine.com has learned. The two split on Sunday, a source tells Us. "They have been having trouble for a while," says the insider. "It's been hard for a long time since Miley has been working so much and traveling a lot." Contrary to reports, Cyrus' ex Nick Jonas "was not the reason for the split, but they have been spending time together." Added the source, "Miley and Nick are working on a couple different projects together. Justin has been a little jealous of that." The 16-year-old Hannah Montana star -- who recently flew to Savannah, where she will be shooting the upcoming Nicholas Sparks drama, The Last Song -- hinted at a split over the weekend when she told Us that Gaston, 20, won't be joining her on the road. "He's got his own thing going on," Cyrus told Us. "But I am just continuing to work hard and definitely have the whole tour going on and my clothing line and the movie." A rep for Cyrus had no comment.
