90210 will no longer have 99 Problems next Monday night, as The CW drama celebrates its 100th episode. In style.

With guest stars Denise Richards, Carmen Electra and Taio Cruz booked, the episode will focus on a charity lingerie show hosted by Naomi at the Playboy Mansion, as this vixen tries to improve her standing with the West Beverly alumni group.

Elsewhere, Silver will perform a burlesque show at the event, while Liam will confide in Annie and also accept Navid's apology for leaking his sex tape.

Dixon, meanwhile, will discover Ade's big secret, which is likely to railroad the plans he had in mind for his new record label. Celebrate along with series in this official network trailer:
