Kelly Osbourne 'frightened and shocked' by Amy Winehouse death

Kelly Osbourne has been left "frightened and shocked" by the death of her friend Amy Winehouse, according to the pop star-turned-reality TV regular's mum.

The Rehab hitmaker was found dead at her home in London last month (23Jul11), aged 27. The cause of death has still yet to be determined, pending toxicology reports.

Reality TV star Kelly Osbourne flew from Los Angeles to London to attend Amy Winehouse's funeral and took to her Twitter.com blog to express her devastation at the sad news.

She tweeted, "i cant (sic) even breath right my now im crying so hard i just lost 1 of my best friends. i love you forever Amy & will never forget the real you!"

Sharon Osbourne admits her daughter is still struggling to come to terms with Amy Winehouse's sudden passing and only time will help her get over the loss of her beloved pal.

The America's Got Talent judge tells People.com, "There's nothing I can do to take Kelly's pain away. This was the first person she's loved who she's lost. That in itself made her frightened and shocked. She's gone through all these different emotions. The only thing that will help her is time."

But Osbourne remains philosophical about life and death.

She says, "It's all a part of life, isn't it? We thank God we're here and we're healthy and we do what we do. But some people aren't as fortunate as us. It's all a part of it. Life and death are as much a part of living, unfortunately."
