Celebs are there most of the time because they have ties to a certain fighter.
Busta and almost everyone at Interscope....Dame Dash and rocafella records all have ties with Winky Wright through Violator and small advertisements that Winky does.
Zab is close to Pacman(titans player),Lil Kim,Jay-z,Young Jeezy,not to mention the countless others linked to the BMF family.
Like someone said earlier about Andre Ward...he is with team Jordan.
So is Roy Jones Jr...Who has a record label which rubs elbows with a sh*t load of rappers.So its common to catch Michael Jordan at Ward and Jones fights...
