Bobby Brown has been keeping vigil at his daughter Bobbi Kristina's bedside since she was hospitalized nearly a week ago, but did take time out for a birthday celebration with family. Unfortunately, that led to a little scuffle that the Atlanta Police Department had to address at about 12:40 a.m. Friday.

According to a newly released police report, an officer responded to a "dispute call" at the Midtown W hotel. From the report:

"Upon arrival, I spoke with Mr. Shayne Brown who appeared to have a laceration to the left side of his forehead. Mr. Brown stated that he was attending a party for Bobby Brown's birthday. Mr. Brown stated that was in a altercation with his mother about a valet parking ticket. Mr. Brown stated that while arguing with his mother, she spit in his face and hit him on his head with a glass bottle. Mr. Brown stated that the altercation took place near the bar area in the W hotel. Mr. Brown further stated that his mother did leave the scene and that he did not want to file any charges on his mother. A manager of the W Hotel was also present to witness the altercation."

A witnesses interviewed by the officer "stated that he did observe Mr. Brown 'swinging' on Tina Brown (his mother) as a result of the altercation."

She had left by the time officers arrived and Shayne Brown drove himself to the hospital, the report said.
