Charlie SheenCharlie SheenHollywood is known for its nasty, bitter break-ups...

So in the midst of all the claws and catfights, it's refreshing to hear actor Charlie Sheen is keeping things amicable with his ex-wife, Denise Richards.

In fact, Charlie has given his blessings to Denise and her new beau, Bon Jovi guitarist Richie Sambora.

Appearing on The Ellen DeGeneres Show, he said: "Well, at least I knew the guy that she wound up with, Richie.

"To know that it's somebody decent and smart and a good parent to be around your children, that's a good thing."

Charlie, 40, also told Ellen he's keeping things positive with Denise, 35, for the sake of his two daughters Sam, two, and Lola, one.
