Kate Beckinsale is in hospital with a ruptured ovarian cyst.
The 45-year-old actor shared a photo of herself from her hospital bed on Instagram, with a breathing tube in her nose and pained expression on her face.
"Turns out a ruptured ovarian cyst really hurts and morphine makes me cry. So thankful to everyone who looked after me #wobbly."
A second picture showed her lying in the hospital bed.
Beckinsale did not share any more information, but replied to her stylist Peter Savic who asked when it happened: "Today!! Thank you darling love you."
A number of Beckinsale's friends and colleagues sent their best wishes. Comedian Sarah Silverman, a close friend and ex of Beckinsale's former partner Michael Sheen, wrote “OMG!!!!”.
Isla Fisher asked: “Are you okay? Sending you so much love?” while singer Natalie Imbruglia said: “Oh no... wishing you a speedy recovery.”
Beckinsale is known for her starring roles in films including Total Recall, the Underworld franchise, and Love & Friendship.
The Independent has contacted a representative for Beckinsale for comment.
