Charlie Sheen Spends Winter Holiday With Denise Richards, Kids

Leave it to Charlie to tweet all about it. Charlie Sheen is spending winter vacation with ex-wife Denise Richards and their two children, plus Denise's adopted daughter, in what appears to be tropical climates. Taking to his Twitter account, Sheen wrote of the rather unconventional get-together on Sunday, tweeting: "what's better than a modern family vacation!?! love spending winter break w/ @denise_richards & my kids!", then posted a picture of a family-style portrait.

On Monday, he followed up with a similarly swoony message: "...all in the family a Christmas.... to remember..! xo c" and another family group shot.

Sheen, 46, and Richards, 40, divorced in 2006; earlier this year, Richards published the book “The Real Girl Next Door,” in which she recounted her marriage with the unpredictable actor whose recent outbursts have landed him in rehab and kicked off the set of "Two and a Half Men."
