Denise Richards has opened up about filming with ex-husband Charlie Sheen for his new sitcom Anger Management.

The actress has been divorced from Charlie for several years now and they have two children together; Sam and Lola.

But she told Good Morning America that although they now have a great relationship, people on the set were a bit uncomfortable having to watch them work together especially as they play lovers on the show.

"It was more awkward for everyone on set watching," Denise laughed. "We looked around and were like, Everyone is staring at us.'"

The pair recently went to their children's baseball game and looked cosy together leading to speculation that there may be a reunion, which Denise has denied.

"Truly, we were just at the game with our kids," the blonde beauty shared. "There is nothing more."

"People are trying to make more out of it. When they don't see us together, we're at each other, but when we're together they think we're back together. But it's for our girls. It's for them."
