Spencer Pratt has challenged Ashton Kutcher to a race on Twitter.

The unpopular star of MTV’s The Hills currently has 194,048 followers on the social networking site. Ashton, on the other hand, successfully surpassed CNN in a race to get 1 million followers as part of a fundraiser for the Malaria No More charity late last Thursday.

Nevertheless, Spencer believes that he can beat the former star of That ’70s Show in a new race.

“Ashton had a huge head start, but I believe in my Twitter family,” he told Us Weekly. “From the moment Ashton accepts my challenge, assuming he’s man enough to do so, whoever adds the most new followers in 30 days wins.”

Spencer says if he loses the challenge, he and girlfriend Heidi Montag will clean Demi and Ashton’s house.

“If I win, Ashton and Demi have to wash my car.”
