So how are we handicapping it?
Pam, 44, has the upper hand on Tara, 35, having logged some Big Brother time already—Anderson appeared on Australian Big Brother, if only for three days. And her Dancing With the Stars experience is likely to come in handy.
And if she can't take it, Anderson reportedly has a contract that states she can leave the Big Bruv (as the Brits call it) house after just five days. The show premieres Aug. 18, so she could make it home well before Labor Day.
Reid, meanwhile, has taking a break from her wardrobe-malfunctioning party time to shoot American Reunion with her old American Pie gang.
And then there's Bobby. We all know what Bobby can get up to.
He's starred in his own reality show, along with Celebrity Fit Club, battled a drug addiction and has landed behind bars. He's guaranteed to spread some insanity around the house.
The rest of the Big Bruv cast includes Big Fat Gypsy Weddings star Paddy Doherty, British trainwreck Kerry Katona and Irish twins Jedward, who reportedly signed a nearly $2 million deal for the gig.
Also joining the shenanigans, the House of Common's speaker's wife, Sally Bercow.
Though we're guessing there's not going to be anything common about this house.
