He continues hurling insults at his former 'Two and a Half Men' boss via Twitter.

Charlie Sheen isn’t done insulting his former Two and a Half Men boss Chuck Lorre.

On Friday afternoon, he Tweeted: “#Adios2&aHalf without me it's like Zeppelin without Plant. The Doors without Jim. C Lorre just elected into the Troll Hall of Shame. RT”

Sheen fired off a nasty letter to TMZ, blasting Loree for attempting to continue the CBS sitcom without him next fall: “The message is crystal clear. NO CHARLIE SHEEN. NO SHOW.”

In the letter, Sheen also referred to Lorre as a "low rent, nut-less sociopath.”

Sheen’s latest outburst is the result of a Hollywood Reporter story Thursday. Sources said Lorre has hatched an idea to reboot the Warner Bros.-produced sitcom with a new creative direction that does not involve Sheen (who was fired from the series in March).

The show’s co-star Jon Cryer has been presented with the plan, as has the studio and network. According to an insider, Lorre has told Cryer this reboot would involve a significant role for him and the introduction of a new, yet-to-be-cast character.

Sheen, who is suing Lorre and Warner Bros. for $100 million, has frequently expressed his desire to return to the show as he crisscrosses the country on his "Violent Torpedo of Truth/Defeat Is Not an Option" comedy tour. A source tells THR that Sheen is still working behind the scenes to be reinstated, attempting as late as this week to set up meetings with Men cast members, hoping to clear the air and win their support. But Lorre is said to remain uninterested in meeting with Sheen, and Warners sources are adamant that Sheen will not be invited back.

Neither CBS nor Warner Bros. has said whetherMen will return for a ninth season, but industry speculation is that the show will almost certainly return.
