Charlie Sheen has lashed out at his ex-wife Denise Richards for ruining a weekend trip to the beach with the couple's two daughters. The actor claims he struggled to enjoy his time with his kids, because he was constantly monitored by Richards' assistant.

The actor and fiancee Brooke Mueller had a court-ordered supervised visit with Sam, three; and Lola, 2; in Malibu on Saturday, amid a fresh court fight over custody agreements.

Sheen recently went public with claims he doesn't approve of the girls' nanny his ex-wife has hired, and he wants more relaxed visits.

And his weekend woes have simply fired him up further. Sheen says, "Here is my and Brooke's weekend with my kids being sullied by one of her (Richards) spies. That is the thing I have to put a stop to. I can't spend quality time - times I'm never going to get again - quite frankly being observed by a perfect stranger."
