As Radar first reported Sunday, Tina was rushed by ambulance to an emergency room because of numbness on her right side. Doctors found "vascular blockages in her neck" and an irregular heartbeat, her rep said. It remains uncertain when she'll be released.
"She's just overwhelmed" by the stress of her niece's medical crisis, the rep said. Adding to her issues, Tina has suffered several heart attacks in the past and has a pacemaker.
The sister of Bobby Brown was socializing with other Brown family members when she fell ill Sunday. She's been in Atlanta since soon after her niece was hospitalized on January 31, holding vigil with other family members and praying for 21-year-old Bobbi's recovery.
Before her hospitalization, however, Tina was at the center of other drama. She was involved in an argument at an Atlanta hotel while celebrating Bobby Brown's 46th birthday on February 5 in which she hit her son Shayne on the head with a glass. Cops were called, but he declined to press charges against his mother.
