He has been laying low after his split from Ariana Grande and a public battle with mental health issues.

Saturday Night Live comedian Pete Davidson attended a Golden Globes after-party overnight, where she was seen flirting and reportedly leaving with British actor Kate Beckinsale.

Davidson, 25, and Beckinsale, 45, were seen "on the patio" at the event and "left together", according to Page Six.

The troubled star split from Grande in October and drew concern from friends when he posted on Instagram about his personal struggles.
