The Hills star Spencer Pratt has challenged Ashton Kutcher to a race on Twitter.
The MTV baddie only has 200,000 followers on his account – a long way behind Kutcher who recently passed the million mark.
That isn’t putting Spencer off though – he reckons he can beat Kutcher in just a month.
If he wins, Ashton has promised to go round and clean Pratt’s house.
Meanwhile, Beyonce’s one star who’s NOT joining the Twitter craze.
Although her little sister, Solange, tweets constantly, Beyonce says the micro-blogging service isn’t for her.
She admits she doesn’t understand it – and because of that she feels like she’s getting really old.
