His birthday might have been three days ago but it looks like Chris Brown is still celebrating turning 23.

The singer was spotted leaving AV nightclub in Hollywood in the wee small hours of yesterday and looked a little refreshed as he got into his car.

Either that or his $7000 Versace jacket was making him feel a little queasy.

His girlfriend Karrueche Tran was nowhere to be seen after helping her beau celebrate over the weekend, tweeting: "Happpppyyy birthdayyyyyyyyy #partystillgoingon"

Lightweight.

It was the second of two birthday tweets she sent to her other half, earlier writing: “Happy birthday my love @chrisbrown!!!”

We bet his ex, Rihanna, loved that, who in an uncharacteristically dry tweet simply wrote: "Happy birthday @chrisbrown" and even managed to resist uploading some saucy snaps.

Maybe she really is over him after all?
