Forbes says differently, but yeah, I'm pretty sure Kelly's is more than that since even Leona has a net worth of 20M and hell, Kelly sure has way more than her.
On the other hand, Kelly said she wouldn't have been able to buy her new house if it hadn't been for foreclosure. So either she bought a freaking castle, or she spent that money already
Or maybe she just had a budget planned for that house and didn't want to pay more although she actually could have.
