Charlie Sheen has fired back at his ex-wife Brooke Mueller in a series of posts on Twitter.com, following her failed attempt to secure a temporary restraining order against him. On Monday (04Nov13), Mueller filed an emergency request to a Los Angeles court to prohibit the former Two and a Half Men star from coming in close proximity to her, but a judge denied the petition and instead set a hearing in December (13) for the former couple to return to court. On Tuesday (05Nov13), Sheen took to the microblogging site to share some unkind words for his ex-wife and her failed legal actions. He wrote, "Oh, by the way, nice try this morning Brooke. You are a chubby weirdo who will lose at every turn trying to get between me and my boys." Muller's emergency restraining order request came days after Sheen's bizarre appearance on U.S. gossip show TMZ Live on Friday (01Nov13), in which he vented his frustration after learning the recovering addict could gain full custody of their twin sons Bob and Max after completing her latest stint in a drug rehabilitation facility. On the show, he claimed he would "empty his 'war chest'" on Mueller and that there would be "a reckoning", which Mueller cited as reasons to enforce the restraining order. The former couple's twins have been under the temporary care of Sheen's second wife, Denise Richards, since May (13), when Mueller was stripped of custody and admitted to a rehab clinic. However Richards recently penned a letter to the Los Angeles County Department of Children and Family Services (DCFS), informing authorities that she can no longer care for the boys.
