On the Net: Kutcher, CNN square off on Twitter

In this Feb. 11, 2009 file photo, actor Ashton Kutcher arrives for the screening of the movie 'Happy Tears' at the Berlinale in Berlin, Germany.

The race for 1 million followers on Twitter is on: In one corner is CNN; in the other, Ashton Kutcher.

Just a few weeks ago, no one was close to reaching that benchmark. Now, as users have flocked to the increasingly popular microblogging site, the numbers have grown.

CNN's breaking news feed (http://www.twitter.com/cnnbrk) is in the lead with more than 945,000 followers as of late Wednesday. Britney Spears and Kutcher were neck-and-neck in second, both with around 910,000 followers.

Kutcher (http://www.twitter.com/aplusk) has seen his followers increase by tens of thousands in the last day.

The 31-year-old actor recently threw down the gauntlet, challenging CNN and its founder, Ted Turner. In a Web video posted earlier this week, Kutcher said he would ding-dong-ditch Turner's house if he beat CNN to 1 million. (For those unfamiliar with the classic adolescent prank, ding-dong-ditch is when you ring someone's doorbell and run away.)

"I find it astonishing that one person can actually have as big of a voice online as what an entire media company can on Twitter," Kutcher said in a video he posted on qik.com. "I just thought that was kind of an amazing comment on the state of our media."

Kutcher later promised a "Guitar Hero" video game to his millionth follower, before quickly realizing it would be difficult to identify such a person.

In postings on Twitter, Kutcher said he was fielding interview requests, including one from CNN's Larry King. He was mulling the offers and claiming it was a "saga for the Internet," not TV.

Not to be outdone, King posted a video on YouTube boasting the wrath of his company and sounding a lot like Ned Beatty's TV network chairman in the 1976 film "Network."

Said King: "Are you kidding? Do you think you can take on an entire network? Do you know how big we are? Do you know what CNN is? Kutcher, you're playing out of your field. You're in another time zone. This ain't gonna work. CNN will bury you!"

CNN, which is owned by Time Warner Inc., didn't have a comment Wednesday. Spokespeople for Twitter didn't return a request for comment.

The CNN breaking news Twitter feed was only recently taken over by the network. A spokeswoman for the network said CNN purchased the address in recent days from the previous owner James Cox.

Cox had been maintaining it himself despite having no official affiliation with CNN. The network said they have been working in partnership with the self-professed news junkie for months.

Both Kutcher and his wife, actress Demi Moore, are popular Twitter users. Kutcher, in particular, is an avid poster of tweets — messages that must be 140 characters or less.

Earlier this month, Internet traffic analyst comScore reported that monthly unique visitors to the site reached 4 million in February, up more than 1,000 percent from a year ago.

Though its numbers aren't up-to-the-minute, the site http://twitterholic.com ranks the most popular profiles on Twitter.

And if you're wondering who's in fourth, the Twitter feed for Ellen DeGeneres and her talk show, "The Ellen DeGeneres Show," is trailing with about 800,000 followers — a number large enough to dance about, at least.

Ashton Kutcher, Demi Moore arrive for screening of "Happy Tears" in Berlin

Demi Moore spends "six figure" on exercise regime annually

Demi Moore spends "six figures" on her exercise regime annually.

The 46-year-old actress - who is married to Ashton Kutcher, 30 - is determined to keep her body in the best shape possible, so thinks nothing of splashing out on expensive fitness trainers and gym memberships.

Revealing Demi's keep-fit regime includes help from a personal trainer who coaches her through a combination of circuit training, weights and Pilates, a source revealed to America's OK! magazine: "The cost per year is in the six figures."

Demi - who wowed onlookers with her toned, slim line physique on the set of 2003 movie "Charlie's Angels: Full Throttle" - denies ever resorting to plastic surgery to help her gain her enviable figure, and those close to her maintain she simply leads a healthy lifestyle.

Her hairstylist Tara Smith explained: "No one has better hair than Demi. It's naturally jet black, not one grey! I attribute it to her healthy lifestyle. She drinks loads of water, eats greens and seaweeds. She doesn't carry a lot of stress."

Her make-up artist Erin Ayanian Mon was equally as glowing, explaining: "She has flawless skin. There's nothing to cover up. We just give her skin a glow with a creme blush and use a lot of sunscreen."

However, Demi has previously revealed one secret to her good looks - she covers herself in blood-sucking leeches to help keep her skin looking fresh.

Hollywood celebrities pledge service to Obama on MySpace

One day before Barack Obama is sworn in as the 44th president of the United States, a host of Hollywood celebrities Monday made pledges of service to the nation in honor of the incoming president on the popular social networking website MySpace.

The celebrities, mostly actors and actresses, revealed their plans to take actions for the change of the United States motivated by Obama's presidential campaign in short video clips directed by actresses Demi Moore.

The videos convey personal, touching and humorous ways in which the entertainment industry plans to give back.

"We are honored to be working with MySpace to rally the entertainment industry to answer President-elect Barack Obama's call to service," said Ashton Kutcher, Moore's husband.

Actors Ashton Kutcher (L) and Demi Moore introduce their Presidential Pledge video at ServiceNation's New Era of Service breakfast, part of the Martin Luther King Jr. Day of Service, in Washington January 19, 2009 leading up to the inauguration of U.S. President-elect Barack Obama.
