Singer and former model Katie Price says she suffered a severe tailbone injury a few weeks ago and was in extreme pain.

The 37-year-old was playing with her five children when she injured the base of her spine, reports dailystar.co.uk.

"I fractured my coccyx a few weeks ago. They were all messing around in Junior's room a few weeks ago and I came in and jumped on the sofa arm, right on the hard bit," she told OK! magazine.

"I was in so much pain and the next morning I couldn't even move. Kieran wanted to call an ambulance! We managed to get there ourselves, but you should have seen the way I was walking."
