… And you say she's just a friend! Patrick Schwarzenegger had some explaining to do after he was spotted get a tad bit frisky with a girl not named Miley Cyrus in Mexico over the weekend.

Patrick and the mystery brunette reportedly danced, wrapped their arms around each other and even held hands while celebrating spring break in Cabo San Lucas. Patrick's girlfriend Miley was nowhere in sight. The Daily Mail even has pictures of Patrick appearing to do a body shot off of the girl.

Patrick, however, was quick to at least try and defuse the situation after pictures started circulating on the Internet.

"Omg. It's one of my best friends girlfriend," he tweeted. He followed that up with another tweet: "Would NEVER do anything against my GF….."

Finishing the trifecta of tweeting, Patrick wrote, "Girls have guy friends and guys have friends that are girls…"

The pictures where taken just days after Patrick brought his girlfriend to dinner with his mom, Maria Shriver, and not long after it was reported that the couple has discussed marriage.

Who knows, maybe Miley, a wild child in her own right, doesn't even care about her man's seemingly flirtatious ways. The "Wrecking Ball" singer will be in Las Vegas at the newly opened Omnia nightclub on March 21. Will Patrick be by her side in Sin City?
