Kate Beckinsale has revealed an embarrassing hotel room injury resulted in her needing to call an ambulance.

The actress, 48, was recently forced to spend some time in hospital following a “mystery accident”.

Opening up about what really happened on The Late Late Show With James Corden, she told the gobsmacked host: “Having done eight or 900 action movies, I hurt myself putting on a pair of leggings in my hotel room.

“It felt like a sort of guitar string snapped and everything was horrible. I mean, worse than having a baby bad, like bad.

“I couldn’t walk, I couldn’t lie down, I couldn’t do anything.”

She continued: “Eventually an ambulance came and they sort of rolled out a sheet and picked me up in it like a sort of sausage and put me on a gurney.”

The Underworld star’s back has since made a full recovery, assuring viewers: “I’m alright now”.

Her dignity however is another matter.
