No More Mr. Nice Guy: Charlie Sheen now slams Ashton Kutcher, his replacement on ‘Two and a Half Men.’

Charlie Sheen: Ashton Kutcher ‘sucks’ on ‘Two and a Half Men’

(NYDN) So much for the kindler, gentler Charlie Sheen.

The 46-year-old actor-turned-winner called TMZ Live late Thursday to declare war on his former employers on CBS’ “Two and a Half Men” and the actor who replaced him — Ashton Kutcher.

“I’m tired of lying…I’m tired of pretending the show doesn’t suck…I’m tired of pretending Ashton doesn’t suck,” he told gossip website.

The tirade comes after old Tiger Blood had taken the high road in recent months, after being replaced on the CBS sitcom “Two and a Half Men” by Ashton Kutcher amid Sheen’s public meltdown last year. That all imploded after Warner Brothers Television, the studio that produces “Two and a Half Men,” sent their former sitcom star a cease and decist letter demanding Sheen stop using a photo from the show to promote his new series, FX’s “Anger Management.”

His attack on Kutcher came just a day after he told TMZ exactly what he thought about their legal salvo.

“I”m thrilled,” he said. “It insulates me from having to redundantly see myself in the idiotic bowling shirt. Perhaps if Warner Bros. spent as much time and energy focusing on their show, it wouldn’t be such a steaming pile of a—.”

A lot can change in one month.

During the Fox “all-star party” for Television Critics Association members in January, Sheen had praised Kutcher’s performance on the show and said, ironically, he had found peace on a show “Anger Management.”

“I think I’m a different person than I was yesterday,” Sheen told reporters at the time. “Everything is a lot more mellow and focused and much more rooted in reality.”
