The husband of Tamra Barney, who stars on "The Real Housewives of Orange County," is filing for divorce, reportedly claiming she cheated on him.

Simon Barney alleges in court documents filed Thursday that Tamra "has been verbally abusive and has committed acts of disloyalty and adultery," reports People.com.

Tamra denies the allegations on her Facebook page, writing: "Thank you to everyone who understands and supports me. For the record, all accusations are false."

The couple has been married for close to 12 years and has two daughters and a son. Simon is pursuing joint custody of the kids and is requesting that the court deny Tamra spousal support, People says. A Bravo network rep had no comment, the site adds.
