Brown Family Crisis: Bobbi Kristina's Aunt Remains Hospitalized With 'Blockages In Her Neck'

Bobbi Kristina Brown's aunt Tina Brown is still hospitalized two days after she was rushed from a Brown family gathering to an Atlanta hospital, her representative tells RadarOnline.com.

As RadarOnline.com 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.

Tina was close to her sister-in-law Whitney Houston and revealed that they had done crack together in an explosive interview with The National Enquirer in 2006.
