Miley Cyrus and Patrick Schwarzenegger apparently have hit a rather large bump in their relationship- possible cheating.

Miley Cyrus Doesn't Think She'd Have Attractive Kids With Patrick Schwarzenegger?

Schwarzenegger is currently on spring break with his fellow college friends in Cabo and TMZ reported Monday on some questionable photos of the 21-year-old with another girl.

Schwarzenegger took to Twitter to clear the air, insisting the girl in the photos with him is his best friend's girlfriend.

He was even shocked he had to defend himself as he tweeted, "Omg."

"Would NEVER do anything against my GF....." he said in another tweet.

The 21-year-old student and model then pointed out that girls can have guy friends and guys can have girl friends.

Schwarzenegger's girlfriend doesn't appear to be sold on his claim though that he didn't and wouldn't cheat on her. Cyrus posted some cryptic messages on Instagram.

The first image she shared said: "Surround yourself with people that reflect who you want to be and how you want to feel, energies are contagious."

Can Cyrus be telling off her boyfriend?

TMZ reported Tuesday that the singer was out and about Monday night at the Laugh Factory in Hollywood and she stayed mum when asked about her beau's photos from Cabo with that girl. Her silence out in Hollywood was also made known on her Instagram as she shared a photo of a girl's mouth stuffed with hot dogs.
