Charlie Sheen not invited to kids' birthday party

Charlie Sheen’s twin sons celebrated their second birthday Sunday but their dad wasn’t invited.

Brooke Mueller and Kathy Hilton hosted a birthday party for Bob and Max at the Hilton family home in Bel Air, California.

Guests included Nicky Hilton and her boyfriend David Katzenberg, and “Real Housewives of Beverly Hills” star Adrienne Maloof.

But Sheen was not there.

The kids ran around the Hiltons’ backyard and played in a big bounce castle.  Guests enjoyed Chinese chow mein and salad served in takeout containers and a chocolate cake for dessert.

And insider told Us Magazine, “There was a lot of security outside at all times to make sure no uninvited guests got in. There was no sign of Charlie at the party.”

“Brooke seemed to have a good time too and was relaxed and happy. She seemed focused on her kids and nothing else,” adds the insider.
