According to TMZ, Toni Braxton's hospitalization stems from her battle with lupus. She has been hospitalized for 4 days. It's unclear if she checked herself in or if she was transported by ambulance.
When Birdman got the news, we're told he hopped on a jet from Texas -- where he was on the road with Jacquees -- to be with her.
Toni and Birdman started dating seriously earlier this year.
She went public with her lupus diagnosis in 2010.
