Ricky Bell -- Bobby Brown's At His Breaking Point

EXCLUSIVE

There's only so much Bobby Brown can take ... which is why his friend of 40 years, Ricky Bell says there's no way to comfort him over the impending loss of Bobbi Kristina.  

Ricky, one of Bobby's New Edition mates explained it's hard to find the right words when he talks to Bobby, because he's suffered so many tragic losses (4 of them) in the last few years. He added ... his heart goes out to the Brown and Houston families.

On Tuesday, Pat Houston and Tina Brown came together for the first time since Bobbi Kristina was hospitalized back in January ... as the families seem to be putting aside their differences during her final days.
