Instead of spending time in the slammer, a “cocky” Charlie Sheen has been partying it up at the Playboy Mansion! A week after narrowly escaping jail time from his domestic violence case with wife Brooke Mueller, the troubled actor joined Hugh Hefner and porn legend Ron Jeremy for the Playboy mogul's annual Midsummer's Night Dream bash on August 7. Though he pleaded guilty to a misdemeanor assault charge in a plea deal that has enabled the Two and a Half Men star to avoid a jail sentence, Charlie hardly seems remorseful for admittedly attacking Brooke last Christmas. “Charlie is cockier than ever. He hasn't gotten in trouble for anything he's done. He's not only relieved, but feels untouchable,” a source tells In Touch. Instead of lying low in the aftermath of his personal and legal drama, the acting legend has not only been out on the town, but also bragging to friends about his enviable cash flow. “Charlie brags that money is not an issue for him,’” the source adds of Charlie, who reportedly earns nearly $2 million an episode for his hit CBS sitcom. The father of five, who must complete 30 days of rehab as part of his sentence, returned to work on set last week.
