Philanthropic stars often write big checks to charities -- but in a new reality series called 'Celebrity Sellouts,' they'll sell off their own possessions to help good causes instead.

The Lifetime series is the brainchild of former 'N Sync member Lance Bass, who's working along with production company DiGaVision -- created by former MTV programming gurus Tony DiSanto and Liz Gateley -- to bring it to fruition.

Deadline reports the show "will follow A-list celebrities in their homes as they part with memorabilia, costumes, furniture and tchotchkes, all of which will be auctioned off for charity, with the celebs trying to hit a goal dollar amount."

And since 'Celebrity Sellouts' is said to be a mash-up of MTV’s 'Cribs' and the popular History Channel series 'Pawn Stars,' it makes sense that DiGa is working with 'Pawn Stars' production company Leftfield Pictures on the new program.

DiGa has certainly made a splash since DiSanto and Gateley founded it about 18 months ago -- in addition to 'Celebrity Sellouts,' Lifetime has also picked up another DiGa series, the aptly-named 'My Life Is A Lifetime Movie,' plus a siblings' singing competition for MTV and a slate of other projects.
