"Big Brother" winner Mike "Boogie" Malin was a scheming, diabolical gamesman on the show but outside the house his antics didn't play well ... because he's now more than $20 million in debt.
The good news ... Mike's a millionaire. The bad news, he's only worth around $1 million and is $23 MIL in debt ... and that spells b-a-n-k-r-u--p-t-c-y.
Mike had a good post-"Big Bro" start ... he was co-owner of 2 Hollywood hot spots -- Les Deux and Geisha House. But then things fell apart. He was sued over a rape that allegedly occurred at Les Deux. And then his partner sued him for embezzlement ... and on and on.
