Talk about a bittersweet Halloween.
No word how long her R&B star beau will be at the facility, but it was just a little more than a week ago that she and the 24-year-old Brown got into that spooky holiday spirit when they checked out Universal Studios Hollywood's Halloween Horror Nights.
Unfortunately, this past Sunday apparently a darker force took hold of the "F.A.M.E." singer, as he is accused of punching 20-year-old Parker Isaac Adams and breaking his nose after the fan tried to photobomb Brown and two women at the W Hotel in Washington D.C.
The Grammy winner, who has denied wrongdoing, was subsequently arrested and charged with felony assault.
But a judge knocked that down to simple misdemeanor assault at his court appearance on Monday, after which Brown elected to seek help, according to his rep, in order to "gain focus and insight into his past and recent behavior."
More than likely, he'll remain holed up in rehab for the next four weeks until he's due back in court on Nov. 25.
