That didn't stop him from making a goodbye video for friends and family just in case, E! News reported.

He was expected to be released from the hospital later in the day.

"We thank everybody for their thoughts and prayers. We really appreciate the outpouring of support," Parks said.

Brown is still hoping to perform at the V100 Taste of Soul concert and festival in Los Angeles Saturday.

Meanwhile, Brown is due in an Orange County courtroom Oct. 22 for a hearing in his ongoing custody battle with ex-wife Whitney Houston over 14-year-old daughter Bobbi Kristina.
