The 25-year-old comedian and 45-year-old actress were first spotted together in January, when they reportedly "hit it off" at Netflix's Golden Globes afterparty.
According to People, Davidson was spotted getting cozy with Beckinsale at the party, with one source saying the "literally cuddled up to each other".
Days later, Beckinsale clapped back at a critic who tried to criticise her for her time with Davidson. Posting a picture of her mother to Instagram, a fan wrote back, "Dear heavens, Kate. Not Pete Davidson.” And without missing a beat, Beckinsale responded, “No, that’s my mother. Easy mistake.”
Earlier this month, Beckinsale was hospitalized after suffering a ruptured ovarian cyst.
“Turns out a ruptured ovarian cyst really hurts and morphine makes me cry. So thankful to everyone who looked after me,” she captioned two Instagram shots of her from her hospital bed, adding “#wobbly.”
