After compromising photos of Patrick Schwarzenegger getting touchy with a female friend in Cabo San Lucas, Mexico triggered cheating rumors, new pics emerged showing Miley Cyrus' boyfriend during the spring break weekend being rubbed with a sunscreen on his back by his ex.

"The 21-year model was pictured receiving a helping hand from an ex-girlfriend as she applied sunscreen on a hard to reach place while partying in Cabo San Lucas, Mexico on Sunday," reported Daily Mail.

Patrick Schwarzenegger and Taylor Burns dated for about a year before he moved on to Miley Cyrus.

"Taylor made sure that the model and actor's upper back was well protected as she applied the cream while seemingly getting flirty with one another," the British tabloid noted.

The article added, "The former couple certainly still seem to have a tightly-knit relationship as they got touchy feely with one another as Patrick often placed his hand on her shoulder while they chatted it up within a rather close vicinity of one another."

It was on the same spring break when Patrick Schwarzenegger was snapped getting cuddling a mystery brunette. Maria Shriver's son then went on Twitter to explain that the lady was his best friend's girlfriend.

In the Twitter post, he wrote that he "would NEVER do anything against my GF....."

He also wrote, "Girls have guy friends and guys have friends that are girls..."

Meanwhile, Hollywood Life alleged that Patrick Schwarzenegger and Miley Cyrus had a huge fight after the cheating rumors.

The source claimed that Patrick Schwarzenegger has been reaching out to Miley Cyrus after the spring break fiasco.

"[Patrick] feels he deserves to give his side of the story with what happened in Cabo San Lucas, and doesn't think Miley's being fair on him," the article claimed.

"He's really angry she won't listen to his side of the story. Patrick's adamant he did nothing wrong, and he just wants to tell Miley that in person. He feels that's the best chance of getting through to her."
