Charlie Sheen, who had kissed Twitter goodbye just a month back, returned to the social media site, on Tuesday, to promote his father Martin Sheen’s appearance on ‘Anger Management’. “It’s on! My pop guest stars Thursday on Anger Management. Watch my dad show up as my dad 9:30p on FX. Best yet!!” the New York Post quoted him as tweeting. The 46-year-old actor included a photograph of him and Martin sharing some laughs and a couple of beers from the set of the FX show. The notoriously troubled actor had quit the popular site on July 13 with a typically bizarre post, “reach for the stars everyone. dogspeed cadre. c out.”
