In a recent Real Housewives of Orange County update, Shannon Beador and husband David are trying to fix their marriage by seeking advice from co-star Vicki Gunvalson.

Avid viewers know that Gunvalson has her share of divorce experiences and she intends to impart the lessons to Shannon. A summary of the latest RHOC states: "After a heated dinner in Mexico, Shannon and David try to get the night and their marriage back on track with the help of Vicki. Back in the OC, Heather expands her family with new puppies while Tamara and Eddie make a final decision about their new addition Astro. Meanwhile, Lizzie pounds the pavement and tries to take her business to the next level."

While she acts as a voice of reason for the Shannon-David marriage, Vicki and her boyfriend finally called their relationship quits. Ayers recently revealed on Twitter what could be the reason of their breakup. He said, "True colors eventually show. I have never given so much yet received so little. #very disappointed #expectedsomuchmore #truthhurts."

In other news, former Orange County star Gretchen Rossi is rumored to return as a guest in one of the RHOC episodes. Gretchen told Wonderwall via a Twitter interview that Bravo indeed asked her if she could make a couple of appearances on the show. The 35-year-old actress wrote on her Facebook account that she particularly likes challenges and that her motto is "never say never!"
