The Real Housewives of Beverly Hills star Dori Kemsley reached her “last straw” with Paul “PK” Kemsley before she officially filed for divorce, a source exclusively tells Us Weekly.

According to the insider, Dorit’s filing was prompted by PK’s recent PDA-filled outing with Shana Wall. “Dorit and PK had promised each other if they were to see other people, they would not be so public for the children’s sake,” the source explains.

PK, 57, was photographed kissing Wall, 50, outside Cipriani’s restaurant in Beverly Hills, California, on April 24, nearly one year after he and Dorit, 48, announced their separation.

One day after PK was spotted with the former Amazing Race contestant, Us confirmed that Dorit filed for the dissolution of their marriage. Dorit is seeking sole legal and physical custody of their two children — son Jagger, 11, and daughter Phoenix, 9 — as well as spousal support.
