Chris Brown called the police after finding a naked intruder in his bed.

The 26-year-old singer returned to his home in Agoura Hills, California, after several days away in Las Vegas - where he'd celebrated his recent birthday - to find a unknown woman in his bed and the words ''I LOVE YOU'' spray painted on the kitchen counter.

Chris and his security team subsequently called the police, who cuffed the woman and she was later booked for felony burglary and felony vandalism, according to TMZ.

The police believe the 21-year-old woman had been in Chris' apartment for a lengthy period of time, as dishes were found in the sink and food was also lying about the property.

The gossip website also reports the woman had vandalised Chris' silver Rolls-Royce and his black Range Rover by spray painting them with the words ''MRS. BROWN''.

Meanwhile, it's been confirmed Chris will not be charged for allegedly attacking a man during his time in Las Vegas.

The 'Loyal' hitmaker was accused of punching a man during a basketball game in the early hours of Monday morning (04.05.15), but law enforcement have now dropped the battery case after the man withdrew his complaint.

A police statement said: ''The victim alleging that he was battered by recording artist Chris Brown has told LVMPD detectives that he no longer wants to go forward with criminal charges.''
