John Mayer and Fergie gave George Clooney a birthday to remember when they serenaded the movie star during a private party in New York on Monday night.

Clooney turned 47 on Tuesday and hosted a post-Met Costume Gala party at Bungalow 8, where he was joined by his girlfriend Sarah Larson, David Beckham, Mayer and Fergie.

Earlier in the evening, the birthday boy co-hosted the fashion Oscars with pal Julia Roberts and Giorgio Armani.
