Bobby Brown has been hospitalized in a "heart attack scare," TMZ.com is reporting.
Brown felt some tightening in his chest and tingling in his arm and had his girlfriend/manager, Alicia, take him to the hospital, the site says.
He was staying with his father in Tarzana, Calif., when he felt ill, and was transported to Tarzana Regional Medical Center, TMZ reported.
Last month, Brown was seeking custody of his teenage daughter from Whitney Houston.
Brown and his attorney asked an Orange County, Calif., court to dismiss a judgment issued in December that ended the couple's marriage and gave Houston sole custody of 14-year-old Bobbi Kristina.
Brown's attorney said Houston has kept him from seeing their daughter and that he deserved custody because he had been her primary caretaker.
Judge Claudia Silbar ordered Brown and Houston to argue their case at a hearing in October before she decides who will get custody.
Houston, 44, and Brown, 38, wed in 1992, when she was at the height of her fame as a Grammy-winning superstar known for hits such as "I Will Always Love You."
Brown, a former member of New Edition, gained solo fame with singles such as "Don't Be Cruel" and "My Prerogative."
During their 14-year marriage, Brown was arrested for drugs and alcohol.
