Patrick Schwarzenegger and Miley Cyrus

Patrick Schwarzenegger is the driving force behind the partying antics of Miley Cyrus.

The couple were recently spotted enjoying a night out at E11even - a 24-hour adult show club - following her concert at The Raleigh hotel in Miami, Florida, on Wednesday night (03.12.14), but a source close to the pair say Patrick - the son of Hollywood legend Arnold Schwarzenegger - is the inspiration behind their wild nights.

An insider told gossip website TMZ: "Patrick has been raging in Miami, organising nightclub and strip club trips with his girlfriend and others and never seems to even take time to sleep."

However, it was claimed recently that Maria Shriver - Patrick's mother - is "very worried" about how her son is being influenced by his new girlfriend.

Maria became concerned after seeing photos of Miley on a bucking bronco shaped like a manhood at her 22nd birthday party last month.

A source explained to the New York Post's Page Six column: "The birthday party with all the penis pictures disgusted her. That was the worst thing Miley could have done.

"Maria is very, very worried about the influence Miley's having on Patrick. She fully believes that you become who you surround yourself with and she's always been so happy with the friends Patrick chooses, she never saw this coming."
