The Season 6 premiere of Bravo's "The Real Housewives of Beverly Hills" is just weeks away. Based on Bravo's first official look at the show's upcoming season, it looks like viewers are in for some serious drama.

As was reported by Us Weekly, the preview kicks off by showing the good times. Kyle Richards, Lisa Vanderpump, Yolanda Foster and the rest of the "RHOBH" crew are shown jetting from Beverly Hills to the Hamptons in New York and even Dubai, United Arab Emirates. They are, for the most part, shown laughing and smiling. The trailer takes a turn for the worst around the one-minute mark when Kyle, 46, is shown preparing for her niece's wedding. She can be seen driving in the car while sharing with someone that she was urged not to come to the wedding. The trailer shows a large focus on Kim Richard's alcoholism and Yolanda's Lyme disease diagnosis. The 51-year-old former supermodel shares with viewers that she "can't remember what it's like to be normal." She's also shown discussing her will with her children in the event that she dies.

The "RHOBH" Season 6 trailer introduces viewers to Erika Jayne and Kathryn Edwards. It was announced that Jayne, a songstress from Georgia, and Edwards, the former wife of NFL star Marcus Allen, would be joining the show months ago. They were cast to replace Kim, 52, and Brandi Glanville. Both women make appearances on the show in Season 6, according to the trailer, although they are no longer full-time cast members.

Kim was fired from the show after Bravo and NBC Universal, the network's parent company, decided she was too much of a liability given her history with alcoholism. She was given the opportunity to seek treatment or forfeit her spot on the show. Although she checked into -- and back out of -- rehab several times between April and now, the network decided to move forward without her. Brandi, 42, quit in June. She made the announcement during an episode of her podcast, claiming she was going to use her newfound free time to focus on other business ventures.

"RHOBH" returns Tuesday, Dec. 1, at 9 p.m. EST on Bravo. Check out the full trailer below:
