Denise Richards claims Charlie Sheen owes her almost a half a million dollars, and she believes he is hiding the money to avoid paying up.

According to legal documents obtained by The Blast, the "Real Housewives of Beverly Hills" star is taking her ex to court and asking a judge to force Charlie to pay what is allegedly owed in back child support for the former couple's two daughters, Lola and Sam.

According to the filing, Denise claims, "[Charlie] has squandered over $24,000,000 from the sale in his interest in 'Two and a Half Men' to pay his personal debts and to support his extravagant lifestyle at the expense of support payments for his children."

She also claims, "During the time frame since our last stipulation/order in 2016 he has failed to pay $450,000 in support while diverting over $600,000 in assets to adult family members and converting thousands of dollars into cash for his own personal use."

Denise does not explain which family members she claims Charlie is working with to "divert" money, nor does she explain the evidence she has to prove he is hiding money.
