All this non-stop partying must be getting to little Rih Rih. Check her out knocked out, dead asleep at her after party in London!

Rihanna performed in London last night and got her party on hard after the show. The singer was seen at  Mahiki Club and didn’t leave until 4am.

Gabrielle Union likes to party. We caught her having a good ol’ time at the “In The Layne” Launch party at DaVinci’s nightclub in Atlanta on Saturday night.
