Denise Richards "So Happy" For Charlie

Denise Richards and Charlie Sheen went through a very public, very painful divorce, during which each said some nasty things about the other while they fought for custody of their kids, Sam and Lola.

But now the Dancing With the Stars contestant has nothing but nice words for her former hubby on the occasion of the birth of his twins with wife Brooke Mueller Sheen.

"I'm so happy for them," she tells Extra. "The girls her two daughters with Sheen are really excited that they're big sisters now. They've already made them a couple pictures and they can't wait to see them."
