Sharon Osbourne appeals for donations for MS charity

Rock matriarch Sharon Osbourne has urged fans to sponsor a team tackling an upcoming charity walk in honour of her son Jack.

The 26 year old was diagnosed with multiple sclerosis (MS) in May and the following month, he went public with his health battle, admitting he is still struggling to cope with his condition.

Now the famous family has been given a boost after Sharon's pal organised Team Jack Osbourne to participate in an upcoming Walk MS fundraiser.

The volunteers will take on the Phoenix, Arizona challenge to generate cash for America's National Multiple Sclerosis Society, which funds research into the condition.

In a post on her Twitter.com page, Sharon writes, "I couldn't be more grateful that a friend has organised a team in Jack's name for a MS Society walk. Get involved," before including a link to a donations page.

The team hopes to pull in £3,100 during the walk on 3 November.
