There's only room for "Two and a Half Men," but three stars mixed it up over the weekend following one big change to the hit CBS sitcom.
Jon Cryer said he was grateful and proud of the work he and costar Charlie Sheen did over the past eight seasons, but is "jazzed" that Ashton Kutcher ("That '70s Show") has signed on to replace the troubled Sheen, who was fired in March.
"Ashton is an extraordinarily talented guy, and his presence will be an asset to our show," Cryer said in a statement, according to USA TODAY.
Sheen, who responded to the casting news with a somewhat sarcastic comment Friday, including hints that the show will tank in the ratings, quickly changed his tune via his Twitter feed: "#Winning Congrats to the cast and crew...CBS & WB..! My best to @aplusk !! The show must go on... You got the right guy!"
And Kutcher, in response to Sheen's tweet, gave a sloppy virtual hug: "#2.5 @charliesheen Thank man. Always been a fan, always will be! BTW you were 'born big.' "
No word yet on how Kutcher exactly will fit into the "Men" mix, but that should change on Wednesday when CBS is to present its 2011-12 broadcast schedule in New York.

Royce, Eminem making noise

Eminem and Royce da 5'9" -- under the moniker Bad Meets Evil -- spent part of the weekend in Detroit shooting a music video for their single, "Fast Lane."
MTV's Swa y, according to images posted to rapradar.com and a short story on mtv.com, also was in the D to talk to the dynamic duo. A big announcement is expected today. The Bad Meets Evil EP is scheduled to drop June 14.

Shriver thankful for support

Maria Shriver wanted to let her fans know that she's thankful for everyone's thoughts following last week's news that she and Arnold Schwarzenegger were separating after 25 years of marriage.
"Thank you for all the kindness, support and compassion," she wrote to her Twitter feed. "I am humbled by the love. Thank you."
This is the first time Shriver, 55, has commented publicly.
