Pop legend Cher is deeply concerned for her ailing mother as she battles a nasty bout of pneumonia.

The Believe hitmaker was forced to jet back to the U.S. from Paris Fashion Week in France earlier this month (Mar13) after her mum Georgia Holt fell ill, and now the singer has shared her worries for the 87 year old's health with her Twitter.com followers.

She writes, "Mom isnt (sic) feeling well! Pneumonia is hard for a young girl of 87... Sometimes I forget she's fragile! I think of her as tough... All the women in my family are tough, as far back as any1 (sic) can remember! She lost weight, I'm jealous! She'll bounce back soon."
