So much for normalcy and structure. Miley Cyrus and Liam Hemsworth, who got back together in September, have called it quits again.
"Their on- and off-again relationship is currently off," a source told People. "But you never know with Miley and Liam. They could be back on at some point."
Friends close to the singer claim she sought comfort in her ex when she first learned of her parents' divorce. But reports circulated last week that said Liam cheated on Miley during a trip to his native Australia.
Is this the basis for the pair's latest break-up? No, says another pal:
"There was no drama. The relationship just ran its course. They were good friends first and remain friends."
Miley's busy schedule might also be to blame. She's currently in Madrid, preparing to perform at the MTV European Music Awards Sunday. From there, it won't be long until she starts shooting on her next film, So Undercover.
