Nine days after revealing treatment, Kate Beckinsale posts hospital bed selfie.

Kate Beckinsale posted another hospital bed photo. The actress, 50, posted a new Instagram Story selfie on Tuesday showing her in bed in blue pajamas with a pillow supporting her head.

After posting about her hospital stay nine days earlier, Beckinsale didn't caption the photo. She hasn't stated her admission reason. After her revelation, Beckinsale's rep declined to respond to PEOPLE.

The Underworld star's beloved cat Willow and Pomeranian Myf have visited her in the hospital.

Beckinsale posted a sweet photo with Myf last Wednesday showing her cradling the dog, who stared up at the camera, on the bed.

The actress titled the image "Visitor," as she did last Tuesday after Willow visited. The photo on Tuesday showed Beckinsale wearing a pink sweater while cuddling her fluffy cat.

After a poignant post on U.K. Mother's Day and her mom Judy's belated birthday on March 11, Beckinsale has been posting hospital updates.

The actress raised concerns when she posted two tearful selfies on Instagram alongside a carousel of photographs and videos. The caption stated she was "sick" but didn't elaborate.

Last week, she captioned the photo, “Happy birthday and U.K. Mother's Day this last week to my incredible mother.” Thank you to those that love and support us when it's bad and attempt to make it better. For caring for our dogs and reminding us of pleasant times when we can't. 

Pink posts a video of a heart on a cloud to remember her late father.
