Patrick Schwarzenegger’s spring break celebrations have probably been ever so slightly dampened, after the 21 year old unwittingly made headlines yesterday, when pictures of him getting close to a mystery brunette were published. Schwarzenegger, who has been dating singer Miley Cyrus since late last year, has now been forced to deny anything inappropriate was going on, after the unflattering pictures became a hot topic online.

Writing on Twitter, The Terminator’s son tried to set the record straight telling his followers. "Omg. It's one of my best friends girlfriend.” “Would NEVER do anything against my GF,” he added, “Girls have guy friends and guys have friends that are girls…”

The 21 year old, who is a student at The University of Southern California, had been partying in Cabo San Lucas, Mexico without Miley to celebrate spring break with his college friends. In one picture he is seen with his arms around the petite brunette, who is wearing a black bikini and a ‘Kappa Kappa Gamma’ sorority bandana.

Since the pictures hit the headlines Miley has chosen not to comment on the directly, however she did post a rather strange rambling message on Instagram Monday, along with a picture of herself and best friend Cheyne Thomas wearing flesh-colored outfits.
