The mum-to-be reveals the Hotel Rwanda star is so convinced he's a winner, he doesn't even ask her to match his odds - or stump up anything at all.
Bell explains, "He plays cards on set all day and there have been more than a few times where he has gotten his per diem or he has 20 bucks in his pocket and just randomly said, 'Wanna bet on this?' And I go, 'Sure,' and he'll make a bet. But I don't gamble anything; I'm not putting any money up. He's got so much bravado.
"When we went to shoot in (Las) Vegas, you get like... $40-a-day for food and they handed it to him and he said, 'You wanna roshambo for this,' which is Rock, Paper, Scissors (hand game). I said, 'Yes.' We did it, I won and took the money... I also won a bunch of his (gambling) chips because he was complaining that he didn't want to stand in line to cash 'em in and I said, 'I'll do it for you...' He said, 'Do you wanna Rock, Paper, Scissors for it?' and I said, 'Sure'. Again, I won.
"I have won $800 from Don Cheadle (and) I don't plan on giving any of it back."
