Sources close to Sara tell us, it all went down last weekend at a friend's house in Georgia -- Tony Stokes accused Sara of being with another man ... and then allegedly choked and hit her.
According to law enforcement, Tony was arrested for simple battery -- and released the next day on $2,000 bail.
Tony's taking it all in stride ... telling us, "Everybody speculates and blows things out of proportion. It's a crazy kind of life. We're dysfunctional. We need our own TV show. I love my wife."
This isn't the couple's first alleged domestic incident -- back in 2009, Sara was accused of stabbing Tony after an argument went nuclear.
