The Orange County Sheriff’s Department has confirmed that Simon Barney, husband of The Real Housewives of Orange County star Tamra Barney, was arrested for domestic battery early this morning. The Sheriff’s Department did not provide details of the arrest, but sources say Tamra called the police after the couple — who are in the process of filing for divorce — began arguing over their dog, and Simon allegedly threw a leash at Tamra and hit her on the wrist. Barney remains in custody on $10,000 bail and is scheduled to appear in court tomorrow. Bravo has yet to respond to EW’s request for comment.
