In wake of the tragic suicide of Russell Armstrong, the Real Housewives of Beverly Hills finally have a reason to celebrate this weekend, as RadarOnline.com has exclusively learned Lisa Vanderpump's daughter, Pandora, is getting married.
"The Housewives were caught off guard with Russell's suicide and memorial, and although it's bad timing, the wedding has been planned for quite some time so they couldn't change it," a source close to the situation told RadarOnline.com.
"Jason proposed to Pandora a while ago, but they're trying to keep everything secret so Bravo can use the story line to fill in the gaps left by Russell's suicide."
According to the source, it will be a classic wedding with a predominantly pink colored theme this Saturday night at the Vanderpump residence in Beverly Hills, with an estimated 275 guests in attendance -- including celebs like Charlie Sheen.
"Wedding guests will enjoy a seven-course dinner of filet mignon or Chilean sea bass," the source said."They will begin with a typical cocktail hour and the ceremony will start around 7:30 p.m., with the Bravo cameras rolling."
The source tells RadarOnline.com that Pandora's fiancé, Jason, proposed to the 24-year-old months ago but the couple has been keeping the details of the wedding under lock and key, especially in light of Russell's untimely death.
"The wedding is expected to go well into the late hours of the night and it's a welcomed distraction for the Housewives from all the recent drama," the source said.
As RadarOnline.com previously reported, Russell's family will be holding a memorial for him in Texas on the same day the Housewives are celebrating Pandora's marriage.
Russell, 47, estranged husband of Real Housewives of Beverly Hills star Taylor Armstrong, was found hanged in the bedroom of his friend's Mulholland Drive home on August 15.
