"Real Housewives of Atlanta" star Brandon DeShezar says he was beat to a pulp by the vicious hands of co-star Apollo Nida this week, and he's lawyering up for a big lawsuit.
DeShazer had a stiff upper lip as he tooled through LAX last night and talked to our photog.
As we previously reported ... witnesses say Apollo attacked DeShazer because he felt like BDS and Kenya Moore had screwed his wife Phaedra Parks over on some workout video deal.
What's motivating him to kick butt in court is not his lawyer ... its an unlikely relative. Check out the video.
