Sanela Diana Jenkins Says She Can Be the "New Villain" of 'RHOBH' Season 12

Following a jaw-dropping 11th season of The Real Housewives of Beverly Hills, which largely focused of Erika Girardi's divorce from Tom Girardi and his subsequent legal troubles, the cast is set to return for a new season on May 11.

The entire Season 11 cast, which includes Erika, Kyle Richards, Lisa Rinna, Garcelle Beauvais, Crystal Kung Minkoff, Sutton Stracke, Dorit Kemsley, and Kathy Hilton (in a friend role) is back, and they are joined by a new full-time housewife, and a very famous "friend."

Months after speculation first began circulating that she was involved with the cast, Sanela Diana Jenkins (who goes by Diana and who is a friend of Lisa Rinna's), is officially the newest diamond-holder for Season 12.

She's joined by fellow new addition Sheree Zampino, who is in an official "friend" role after making a few cameos on the 90210 series over the years. While Sheree is known for her past marriage to Will Smith and for her prior reality role on Hollywood Exes, viewers may not know as much about Diana.

Read on to find out more about the Season 12 star's business life, and her personal life.

Sanela Diana Jenkins (née Ćatić) was born in Sarajevo in Bosnia in the '70s. The entrepreneur is the eldest of two children, and her younger brother died at the age of 21 during the Bosnian War.

She was an economics student at the University of Sarajevo in the '90s as well, but she left her home country behind once the war broke out in 1992. Diana spent a year as a refugee in Croatia, and she later moved to London.

She was ultimately able to continue her studies in Economics and in Computer Science at City, University of London.

Diana met Roger Jenkins, a British financier, at a gym near her London campus. At the time, Roger was working as an executive for Barclays. The pair wed in 1999, and they welcomed two children together, Eneya and Innis, before they divorced amicably in 2011.

Roger has since gotten remarried to Larissa Andrade, and Diana has a daughter named Eli with her partner, musician Asher Monroe.

The RHOBH addition has been successful in her professional life as well. While she was living in London, Diana partnered with Melissa Odabash for the designer's eponymous line of luxury swimwear.

Diana is the creator and founder of Neuro Brands, which is an international line of non-carbonated, flavored health drinks.

She is also known for producing the 2009 coffee table book, Room 23, which features photographs of celebrities taken in the Peninsula Hotel in Beverly Hills. Deborah Anderson, a photographer in Los Angeles, took the pictures for the book, which showcases the likes of George Clooney, Cindy Crawford, Lindsay Lohan, and Elton John.

The proceeds from the book went toward several philanthropic efforts, like the Sanela Diana Jenkins Clinic on International Justice, and the Irnis Catic Foundation.

In addition to her business and charitable endeavors, Diana is adding to her resume with her spot on the Bravo series.

In the RHOBH Season 12 trailer, which dropped on April 7, Diana can be seen getting involved in a bit of drama with Sutton Stracke.

"I think you're a soulless person," Sutton says to Diana in one scene from the clip.

"You need a new villain?" Diana responds. "Here I am."

It remains to be seen why the two are feuding but, if the trailer is any indication, Season 12 will be very dramatic.

The new season of RHOBH will kick off on Bravo at 8 p.m. on May 11.
