'Baseball Wives' Star Anna Benson -- Arrested for Felony Assault After Alleged Gun Threat

Former "Baseball Wives" star Anna Benson -- the estranged wife of ex-pitcher Kris Benson -- was arrested this morning in Georgia ... after allegedly raiding Kris' apartment with a gun and a metal baton, all while wearing a bulletproof vest.

According to law enforcement, Kris -- who filed for divorce last year -- reported that Anna showed up in a rage last night after being forced by the court to vacate their marital home. Kris says Anna arrived and immediately whipped out an "expandable metal baton," threatening to hit him.

But it didn't stop there ... Kris told police Anna then pulled out a handgun and demanded money. She must have been expecting Kris to pull a gun on her too ... because she was allegedly wearing a bulletproof vest at the time of the alleged assault.

According to the police report, Kris told Anna he would get her the money following the altercation ... but then left the home and called police instead.

Anna -- a former FHM model -- was arrested this morning and booked on 4 counts ... 2 counts of felony aggravated assault with a weapon, 1 count of criminal trespass, and 1 count of possession of a firearm during the commission of a crime.

She is currently still in custody. Anna is famous for her outlandish behavior on "Baseball Wives" ... including pulling out a 12" dildo and threatening to hit her castmates with it. She also famously threatened to sleep with the entire Mets team if Kris ever cheated on her.
