Sharon Osbourne has said sorry for insulting Britain's Got Talent runner-up Susan Boyle on a US radio station.

Osbourne stated on micro-blogging site Twitter that she wanted to "apologise for getting a cheap laugh" at the Scottish singer's expense.

Earlier this month Osbourne, 57, appeared on Sirius XM Radio where she called Boyle a "lovely lady" who had been hit by "the ugly stick".

The clip, which was posted on YouTube, angered some of Boyle's fans.

In another glimpse into the twisted life of Lindsay Lohan, her parents Michael and Dina argued over how bad the situation with their daughter was, and Dina admitted that Lindsay had been cutting herself. The shocking bombshell is revealed in the recorded audio tape exclusively obtained by RadarOnline.com of a phone conversation between Dina and Michael, where the two blame each other for Lindsay's dire situation.

Michael is talking with Dina, telling her that he represents the bad things in her life and Dina interrupts him, saying "Her cutting herself and hurting herself? Yeah, it's bad Michael, it's bad." Lindsay has been photographed over the years and recently with scars on her wrists, a sign of the cutting, which is a desperate cry for help from the troubled starlet.
