It looks like it could be another failed romance for the Queen of Twerk.
Miley Cyrus and Patrick Schwarzenegger have only been dating for four months, but sources say they're moving fast - very fast.
In fact, last week it was reported that Miley and Patrick are talking marriage.
The news wasn't all that surprising, as that's sorta Miley's MO. After all, she got engaged to Liam Hemsworth when she was just 19.
Those two never never made it to the altar, of course, and they eventually parted ways amidst rumors of infidelity.
Now - if a handful of unidentified sources are to be believed - it looks like Miley's relationship with Patrick could meet with a similar fate.
Radar Online is reporting that Patrick was spotted getting close with a bikini-clad brunette during a recent beach party.
Insiders claim photos that will soon be made public show Patrick kissing, embracing, holding hands with, and even doing body shots off of the mystery woman.
Patrick has already responded to the controversy on social media, tweeting, "OMG. It's one of my best friends...Would NEVER do anything against my GF."
Naturally, Patrick is taking a lot of flak from Miley fans, many of whom have brought up the topic of the Arnold Schwarzenegger cheating scandal and suggested that the apple doesn't fall far from the tree.
It's a low blow, but when a guy is half Kennedy, half Schwarzenegger, it's hard to ignore his family's history of philandering.
