Sheen's ex concerned about his 'difficult' behaviour

Denise Richards is “learning how to deal” with Charlie Sheen’s behaviour.

The ‘Two and a Half Men’ star’s ex-wife - with who he has daughters Sam, six, and five-year-old Lola – admits she is “concerned” about the 45-year-old actor’s recent wild antics, including reports of drink-and-drug fuelled parties with escorts, and admits it can be “difficult” stopping their children finding out.
