Chris Brown’s transition from 25 to 26 is going anything but smoothly.

The singer arrived home from a birthday weekend in Las Vegas to find a mysterious naked woman in his bed, reports TMZ.

Brown and his security team arrived at his Agoura Hills, Calif., residence on Wednesday to find a woman’s clothes in the entryway and “I LOVE YOU” spray-painted across his kitchen counter, according to the website.

After further investigation, the group found an unknown naked 21-year-old woman in the “Loyal” singer’s bed. Brown then called the police, who took the woman into custody and booked her on felony burglary and vandalism charges.

The R&B star, whose birthday was on Tuesday, posted a picture of the woman wrapped up in a towel to his Instagram account, along with a description of what she’d allegedly done, including throwing out all of his daughter’s and dog’s belongings, placing “voodoo things” around the house, and spray-painting her name on his cars.

“I love my fans but this is some on some real real crazy s–t!” he wrote. “I pray she will get help.”

Police believe that the woman had been holed up in the residence for a few days, after they found dishes in the sink as well as discarded food, TMZ reported.

The unnerving discovery comes just days after Brown was investigated for punching a man during a basketball game at the Palms Casino Resort in Las Vegas. The case was dropped after the man withdrew his complaint against the singer.
