Miley Cyrus & Justin Gaston's Split Confirmed

Miley Cyrus and Justin Gaston have called it quits, sources confirm.

“They broke up on Sunday,” an insider confirms to JustJared.com. “She’s now in Savannah filming [her new movie The Last Song] for three months.”

E! Online reports the split was caused by Miley‘s ex-boyfriend, Nick Jonas: “She obviously has been hanging out with Nick again a lot, and Justin was cool with it at first, as long as it was just a cool, friendly thing. She didn’t cheat, but I guess Nick was trying to get her back the whole time.”

Miley was last seen hugging Nick on Saturday while shooting their new music video, “Send It On.”

Miley tweeted the day of the break-up, “”I hope that I’m dreaming, cause I’m sick of this feeling. Tears are words the heart can’t express. Why does saying good-bye hurt so much? Daddy’s giving me therapy. Life will go on. You will smile again…. we will smile again.”

Justin added, “I almost fell asleep. I think I did for like 10 seconds. Obviously it didn’t work out. How many tears are in there? They’ve gotta run out soon right?”

Sadness!
