Brandi Glanville was in Las Vegas this weekend, and, as expected, things got a bit crazy.

After landing in Sin City, Glanville lost one of her friends, Mark Hasche, and quickly took to Twitter, where she revealed the shocking turn of events to her fans online, and attempted to locate her friend.

"WTF - where the fuck are you-last time I saw you....," Glanville wrote, along with a dark photo of herself and Hasche.

Hours later, Glanville located Hasche, and quickly took to Twitter for a second time, where she shared a photo of the hairdresser, and revealed he had been found. Then, she attempted to explain his odd disappearance to a fan.

As Glanville and her friends enjoyed their trip to Las Vegan, Glanville's friend, Kim Richards, was in Los Angeles, where she celebrated her 51st birthday with two of Glanville's nemesis, Kyle Richards and Lisa Vanderpump.

Because of one of Glanville's earlier tweets, fans expected Richards to be with Glanville on her birthday, but it appears she had a change of plans.

Glanville has since returned to Los Angeles to be with her two sons, Mason and Jake.
