Charlie Sheen isn't proud of his behavior leading up to his firing from Two and a Half Men last year.

In an appearance on NBC's Today show on Thursday, Sheen said his actions, which included repeated rants against Two and a Half Men creator Chuck Lorre, were "a little cringeable because I didn't recognize parts of who that guy was."

Sheen is now the star of the FX comedy Anger Management, premiering June 28. He told Today anchor Matt Lauer he discussed his recent past with the cast and crew on their first day on the set, and they had a good laugh about it.
