Katie Price Shares Post-Sickness Bum Selfie

Katie Price has taken the concept of the "belfie" (bum selfie) to a new level, tweeting a snap of herself with no undies on at all.

And the glamour model-turned-reality TV star told fans that she was sporting a slimmer figure following her recent mystery illness.

She wrote: "Being ill has defo made me lose weight".

The 35-year-old was rushed to hospital before Christmas after feeling under the weather for some time.

But although she has still not revealed what the issue was, she now appears to be back to normal.
