Sharon Osbourne has apologised to Susan Boyle for insulting her on a US radio station.

Osbourne, 57, had insulted Boyle, 48, on Sirius XM Radio and said she was a ‘lovely lady’ who had been hit by ‘the ugly stick’.

She then insulted her further and said: “You just want to say God bless and here’s a Gillette razor.”

However Osbourne has now apologised for her comments.

She took to her Twitter page to post an apology, writing: “Susan Boyle is a lovely gracious woman and I took advantage of that by poking fun at her.

“I would never want to be responsible for hurting Susan and I must apologise for getting a cheap laugh at her expense.”

Dancing With The Stars contestant Kelly Osbourne has revealed the show has given her insomnia.

Kelly, 24, recently made her debut on the American TV show and she admitted she just can’t get to sleep as her routines are constantly playing on her mind.

She wrote on Twitter: “I can’t sleep, keep going over samba steps in my head!”

Kelly made her debut on the show with an “impeccable” waltz that brought her mum Sharon to tears. However, her second-week dance did not receive such rave reviews and she was awarded less flattering scores.
