The comedian has just split from model wife Lara Stone but managed a smile for photographers as he left London's exclusive Arts Club on Tuesday night (10 March).
David was joined by BGT judges Simon Cowell, Amanda Holden and Alesha Dixon, as well as X Factor's Louis Walsh and Simon's girlfriend Lauren Silverman.
It's good to see David looking happy after a difficult start to the year.
Claims emerged this month that David and model partner Lara were embarking on a trial separation, with Lara moving out of their family home with son Alfred, two, and their dog.
Reps for David told Reveal they don't comment on his private life.
The ninth series of BGT is scheduled to begin soon on ITV, with Ant & Dec returning to host and Stephen Mulhern back fronting the spinoff show.
Collabro won the last series of the show.
