When actress Ellen Barkin divorced Ron Perelman in 2006, she received between $20 and $60 million. But now, according to The Smoking Gun, the star is suing her ex-hubby for $3.4 million, claiming that he promised to fund her film production company. He was supposed to invest $4 million — so far he's only coughed up $468,160. One one hand, you have a woman who, clearly, is not hurting for cash.
