It's really over! Just one month after announcing their separation, Shannon Beador has filed for divorce from her cheating husband David, Breaking Celebrity News can confirm.

According to Orange County Superior Court records obtained by Breaking Celebrity News, the Real Housewives of Orange County star, 53, filed "dissolution with child" papers against her hubby of 17 years on Friday, December 1.

In addition to the petition, the mother of three teen daughters filed a custody declaration and income and expense declaration.

Sources told Breaking Celebrity News that she is going after full custody of their kids, and a generous spousal and child support arrangement.

David, 53, has not yet responded to Shannon's petition.

The Blast was first to report the filing.

As Breaking Celebrity News exclusively reported in October, heartless David — who admitted to carrying on a secret affair in 2015 — moved into a bachelor pad and immediately started dating other women after their secret split five weeks before the public confirmation.

The fallout will definitely unfold onscreen. While Peggy Sulahian and Lydia McLaughlin will not be returning next season, sources told Breaking Celebrity News that Shannon will most certainly be coming back to the Bravo hit.
