'Real Housewives' star arrested after brawl

You know there's always drama when it comes to any of the Real Housewives.

But on March 27, things got physical on a Real Housewives of Atlanta reunion show.

According to CNN and other reports, Porsha Williams, who is in the middle of a nasty split from NFL star Kordell Stewart, got into a brawl with castmate Kenya Moore while shooting the show.

The two have been going at each other for years, says Us Weekly. In November 2012, Moore called then-newcomer Williams "naive" and a "heifer."

During the reunion taping, there was apparently hair-pulling and other scuffling. Host Andy Cohen said in a blog post that "it started to escalate" and several people jumped up to stop it, including him. "It came out of nowhere."

Apparently police weren't called at the time, but Moore decided to file a police report.

An arrest warrant was issued.

Williams, 31, turned herself in on Wednesday to the Fulton County (Ga.) Sheriff's Office to be booked on misdemeanor battery charges. TMZ says she was immediately released after posting $2,000 bail, but not before posing for a really beautiful mug shot.

And, of course, you can see it all on Sunday's Real Housewives of Atlanta reunion show on Bravo at 8 p.m. ET/PT.
