The Outkast star reportedly signed a $450,000 (£300,000) deal with network bosses at Channel 5 to appear in the fly-on-the-wall reality series, which will begin airing later this month (Aug13), but Big Boi claims the announcement he'll be a part of the show is premature.
In a statement issued to the Wall Street Journal, the hip-hop veteran explains: "They (Big Brother producers) reached out to my team a while back. I was on my way back from Canada, they started saying I was set to be on there... and it wasn't true."
However, Big Boi isn't ruling out the Tv gig completely, adding: "I don't know. I've been on the road... They were talking to my team but I don't know what happened after that. I never said yes or no, ever."
If the rapper signs up for the show, he will join British 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 series.
Big Boi wouldn't be the first hip-hop star to take part in Celebrity Big Brother - Coolio and singer Sisqo have both previously featured on the U.K. programme.
