His influence is rubbing off! Miley Cyrus shows her caring side at charity event with boyfriend Patrick Schwarzenegger

Perhaps having the approval of her boyfriend's mother Maria Shriver is worth having after all.

Miley Cyrus made an effort to please as she joined Patrick Schwarzenegger at the Brooks Brothers Celebrates The Holidays With St. Jude Children's Research Hospital And Town & Country in Beverly Hills on Saturday.

The 22-year-old singer traded stripping down and making out in public with Arnold and Maria's 21-year-old son for some charitable time to benefit the famous children's hospital.

Miley was the picture of sweet compliance as she posed with 13-year-old DJ Oscar Adler, who is the son of music producer Lou Adler.

Her platinum blonde pixie was mostly covered up in a grey knit cap and her figure, which she's never afraid to flaunt, was bundled in a bulky black coat.

She wore no make-up and preferred the fresh-faced look with just a hint of neutral lip gloss.

It was a relatively demure scene for Miley and Patrick following their romantic getaway to Miami, Florida last weekend during Art Basel.

The couple was inseparable and partied it up at the upscale strip club 11even on three consecutive nights, according to PageSix.

On Friday, Miley also caused eyes to pop while on stage performing during the Tommy Hilfiger and Jeffrey Deitch party at Raleigh by stripping down to pasties and thong, and smoking what looked like a joint.

Of course, Rachel Zoe was on hand to lend style while clad in a shaggy black waistcoat, black-and-white striped blouse and black trouses.
