Kate Beckinsale was rushed to the hospital Friday in Las Vegas. 

After staying silent all weekend, the actress took to Instagram on Sunday to share an image of herself in a hospital bed. The snap shows a close-up of her face with her arm dramatically draped over her forehead. On it, followers can see a hospital wristband as well as an IV. 

"Feeling a lot better. Thank you so much for your kind messages and love x," she captioned the image without going into detail about why she was hospitalized.

The 48-year-old actress has been staying at the MGM Grand while filming for "Prisoner's Daughter," according to TMZ. Beckinsale was reportedly rushed to the hospital after her back gave out.

It's unclear what her current condition is, but the star is reportedly still in the ER.
