Osbourne has to put beloved pet to sleep

Kelly Osbourne has been left devastated after learning she'll have to put her pet dog Noodles to sleep.

The pooch fell ill earlier this week (beg13Jun11) and Osbourne took to to tell followers of her worst fears, and on Wednesday (15Jun11), they were realized when the singer-turned-TV personality was told she'd have to put her pet down.

Tweeting the terrible news, Osbourne wrote, "noodles is not going to make it. she was born with a brain defect and i have to put her to sleep today im devastated. i just cant believe it."

The dog's illness was sparked by a seizure on Monday.

It has been a rough few weeks for Osbourne - her other pet Sid had to be rushed to the vet last month (May11) after eating half a packet of chewing gum. The star overcame a bad illness herself only to fall and break her foot.
