Ashton Kutcher has beaten news giant CNN and Britney Spears to become the first Twitterer to have one million followers.

The Punk'd star, whose postings have included a picture of his wife Demi Moore's bottom, celebrated hitting the six figure mark with an online video via his webcam.

And Demi - also a frequent Twitterer - made an appearance on the webcam during the last stages of the online race.

Ashton agreed to give 10,000 mosquito bed nets to charity for World Malaria Day if he won and 1,000 if he lost. Check out his victory video below.
