LOS ANGELES: Actress Demi Moore, who announced late last year that she was ending her marriage to actor husband Ashton Kutcher, has finally made the split official...by changing her Twitter name.

“So hard finding a name that was fun somewhat playful and available. So for now it will be @justdemi It could grow on me!” Moore said on the popular microblogging site, dumping her old user name - @mrskutcher.

“Thanks everyone for your help in finding my new name!” she tweeted to her more than five million followers.

The 49-year-old Moore was treated for “exhaustion” in January, two months after the couple split amid reports of Kutcher's infidelity with a woman less than half Moore's age.

A call to emergency services released in January features one woman telling the operator that Moore “smoked something, it's not marijuana but it's similar to incense... and she seems to be having convulsions of some sort.”

Moore and Kutcher, 34, announced their separation in November, after months of media reports about problems between the couple, who married in 2005. She had earlier been married to actor Bruce Willis for 13 years.

The actress made her name in movies including “Ghost” (1990), “A Few Good Men” (1992), “Indecent Proposal” (1993) and “G.I. Jane” (1997), as well as for a 1991 Vanity Fair magazine cover photo of her naked and heavily pregnant.

Kutcher is best known for TV shows including “That 70s Show” and “Punk'd,”and last year replaced troubled actor Charlie Sheen in the popular comedy “Two and a Half Men.”
