When the recently renewed The Real Housewives of Beverly Hills returns to Bravo for season seven, there may be a brand-new face on the 90210 block.

Sydney Holland, the ex-girlfriend of Sumner Redstone who was famously ousted from the 93-year-old mogul's mansion last fall, has formally pitched herself to join the cast of the reality show, sources tell The Hollywood Reporter. Holland, 44, is now in the running to appear alongside stars Lisa Vanderpump, Kyle Richards, Yolanda Foster and Lisa Rinna.

Though no decisions have been made, Holland — who was with the billionaire Viacom and CBS mogul for five years — has a backstory that rivals any in the ZIP code. After being introduced by Millionaire Matchmaker star Patti Stanger, Holland began dating Redstone and quickly established herself as an influential figure in his life. Along with longtime Redstone companion Manuela Herzer, Holland was a regular presence at his mansion, traveled with him and bought real estate using the millions of dollars in gifts the mogul gave her.

In a 2014 interview with THR (likely the last the frail mogul will ever give), Redstone sat with both Holland and Herzer by his side. And last year, Redstone's former driver detailed the extent of influence Holland had over Redstone and the staff at his mansion. The driver also wrote that Holland had personally instructed him to deliver cash to various women around Los Angeles.

But last fall, Holland was abruptly ejected from Redstone’s Beverly Park estate for allegedly having an affair with a former actor and flying to and from Arizona on private jets to see him. She has since gone quiet as the succession issue at Viacom has exploded in litigation and maneuvering. Holland declined to join Herzer's legal effort to be reinstated as Redstone's health care provider when Herzer also was ousted from Redstone's life.

One source says Holland or her reps have created a "sizzle reel" — a promotional video for casting executives — that was presented to Real Housewives producers. Bravo declined to comment on the Housewives casting process and Holland did not respond to requests for comment.
