Ashton Kutcher and CNN are competing to see who can first reach a million followers on popular social networking site, Twitter.

Kutcher challenged CNN to the race with a Web video posted on Tuesday. If he wins, Kutcher says he will ding-dong ditch CNN founder Ted Turner's house and post the video of the prank online.

The actor has also thrown in an incentive to his millionth follower. Electronic Arts will make the winner a star in its upcoming video game The Sims 3 and give them a free copy of every single game EA makes in 2009. He later said that if he wins, he will also donate money to the fight against Malaria in Africa by donating 10,000 anti-mosquito, bed nets for African families.

CNN and Kutcher are both expected to reach one million followers sometime today.

As of 12 p.m. ET, Kutcher's Twitter account had 953,287 followers, putting him in third place in the number of followers.

Kutcher tweeted on Thursday that EA would only give the prize to the millionth follower if he beats CNN.

I found it astonishing that one person can actually have as big of a voice online as what an entire media company can on Twitter, Kutcher explains in a video as to why he made the challenge.

According to Tweetrace the top 5 are currently @cnnbrk (CNN), @aplusk (Kutcher), @britneyspears, @theellenshow and @johncmayer.

No single Twitter account has attracted 1 million followers, according to TwitterCounter and Twitterholic, two sites tracking the most popular Twitter users.

CNN's Larry King accepted Kutcher's challenge and said boldly that CNN would win. Watch that video clip on the next page:
