"I hope this isn't true," Demi wrote in response to the planned Twitter series, announced over Memorial Day weekend. "If it is our Twitter time may come to a quick and sad end!"
Adding, "This would not be a smart move for Twitter!"
As previously reported on Access Hollywood.com, The social-networking service said Monday it has teamed with Reveille productions and Brillstein Entertainment Partners to develop an unscripted series based on the site, which invites 140-character postings from members around the world. The show would harness Twitter to put players on the trail of celebrities in an interactive, competitive format.
And though it may seem like everyone in Hollywood is addicted to Twitter, some celebrities are steering clear of the Web site. According to USA Today, Kanye West, Zac Efron, Katie Couric, "Southland's" Ben McKenize, Beyonce and Drew Barrymoore are some of Hollywood's hottest who are still cold about telling the world their every move.
"I don't have a Twitter, a MySpace or a Facebook or anything like that," Zac recently told People. "I kind of value in people not knowing where I am or what I'm doing."
He added that his Twitter updates wouldn't be worth posting, saying, "I'm on the toilet. Still on the toilet. Guys, dot-dot-dot, out of TP. Still on the toilet."
