Miley Cyrus and Patrick Schwarzenegger 'on a break' - report

Miley Cyrus and Patrick Schwarzenegger have reportedly decided to take a "break" from their relationship after just five months of dating.

Rumors of a split between the Wrecking Ball hitmaker and her beau have been floating around ever since Arnold Schwarzenegger's son was photographed closely embracing a bikini-clad female during a vacation in Mexico last month (Mar15).

He later slammed the reports on Twitter.com, writing, "Omg. It's one of my best friends girlfriend... Would NEVER do anything against my GF."

But now, multiple sources tell Us Weekly that the two have decided to take some time apart, with one insider saying, "The scandal did its damage. They both saw sides of each other they weren't pleased with but they were trying to make it work."

Cyrus and Schwarzenegger have been dating since November (14).
