Outkast rapper Big Boi is set to follow in the footsteps of fellow hip-hop stars Coolio and Sisqo after signing up to appear in the latest series of the U.K.'s Celebrity Big Brother. The star, real name Antwan Patton, has inked a $450,000 (£300,000) deal with bosses at Britain's Channel 5 network to join the fly-on-the wall reality TV show, which will begin airing later this month (Aug13). A source tells Britain's the Sun, "Producers always like to mix things up with an American star and they hope Big Boi will do the business this year." Big Boi will join other celebrity contestants including Five singer Abz Love and model Sophie Anderton. Whitney Houston's daughter Bobbi Kristina Brown is also reportedly on board for the 12th season of the show.
