Ashton Kutcher has put his Twitter foot in it once again after he ended up in a feud with his fans.

The actor and his wife, Demi Moore, have become more famous for their posts on the social networking tool rather than their films of late. But Kutcher has been left red faced over a Twitter he posted.

After hearing that a sportsman refused to give a child fan his autograph, he wrote, "Truth. Autographs R annoying."

However, he had to perform a U-turn after his fans got upset by his remarks. He quickly wrote back, "If ppl ask and I'm not late 4 something, it's cool"

It's not the first time Kutcher has ended up in trouble after using Twitter. He had to apologise to his neighbour after complaining of the construction work noise next door to his fans.
