Miley Cyrus has split up with Patrick Schwarzenegger. The 'Wrecking Ball' hitmaker has called time on her relationship with the USC student for good. A source confirmed: "It's not a break. It's done." While Miley, 22, has been spending time in the studio in recent weeks, Patrick was spotted partying at the Coachella music festival and it appears the couple's differing priorities were behind the split. The insider added to PEOPLE: "They're just in two different places in their lives - he's in college and she's focused on her music and career." It is thought the pair had been going through a rough patch after Patrick was spotted cosying up to another woman while on holiday in Cabo San Lucas, Mexico, last month.
