Cast member of The Real Housewives of Beverly Hills Brandi Glanville announced on Wednesday via Twitter that she became a New York Times bestselling author.  

"Ok I'm crying! I'm a New York Times best selling author! I'm crying like a baby. Thank u thank u thank u!" she tweeted.

The mother of two is currently traveling to promote her book Drinking and Tweeting: And Other Brandi Blunders. She was spotted on Wednesday arriving in LAX wearing a long sleeved pink dress, short black boots and sunglasses. She accessorized the look with a black cardigan, and a white handbag. Daily Mail noted that she was scheduled to do a book signing at The Grove, a shopping center in Los Angeles, that same day. She then travels to Las Vegas, Nev., on Friday. 

In the reality series she stars in, Glanville is close friends with fellow cast member Lisa Vanderpump. A show insider told Radar Online Wednesday that the two women are the only ones safe from being fired from the show. 

"The only cast members guaranteed to come back for the fourth season of the smash hit reality franchise are Brandi Glanville and Lisa Vanderpump," the insider said. 'It's no secret that Adrienne Maloof and Taylor Armstrong were already on the outs - but the other ladies, including Paris Hilton's aunts, Kim and Kyle Richards, and Yolanda Foster are also on the chopping block."

The source added that the show's Bravo producers "are looking for over-the-top cast members" and that they "would love" to add on to the show Lionel Richie's wife Brenda and Sylvester Stallone's wife Jennifer. 

Different sources told TMZ that Armstrong will likely be fired from the show and replaced by two other women: former Extra host and Plastic Wives star Dayna Devon, and also Ron Stewart's wife Penny Lancaster.
