Episode 12 of The Real Housewives of Beverly Hills aired Monday in which most of the women take a trip to Las Vegas except for Adrienne Maloof, who stayed behind to work and also because she was not invited on the vacation.

Brandi Glanville hosted a trip to Las Vegas and treated all the women and some of her other friends to a few days in the sun and a pole dancing class taught by a professional dancer. Kim Richards did not make the trip because she said she felt that, as she puts in an effort to keep up her sobriety, she did not feel Las Vegas would be a safe environment for her.

The only other Housewives star not to make the trip was Maloof.

In her Bravo blog, Glanville spoke on Monday about her decision not to invite Maloof on the trip, saying it was "due to our legal issues." She then went on the made negative comments about Maloof's new business venture- her own handbag collection.

"Adrienne has many, many, many business ventures going on that she is investing money into...that say Maloof all over them. . .I hope she makes money from those purses, but the only initials I want on my purses are LV," Glanville wrote.

She then added that she would not invest her money into anything, and "especially not purses with my name plastered all over them."

The model and mother of two also talked about the comment that aired in episode 12 about Maloof owning only 2 percent of the Palms hotel in Las Vegas. Glanville said it was "a b--chy comment, but a true statement," and added, "I probably wouldn't have said it had Pandora's bachelorette party not been brought up and Adrienne not been threatening me with a lawsuit."

In a preview clip for episode 13, Maloof denied filing a lawsuit against Glanville. When accusations were thrown about the matter, Maloof said to Glanville "shame on you" and Glanville replied back, "Are you kidding me? Shame on you."
