The paparazzi honed in on Katy Perry and her entourage at a pre-Grammys party in L.A last night as the singer laughed and got a bit silly for the cameras.

Katy was accompanied by fiancee Russell Brand and close friend Rihanna as well as party buddy Taylor Swift – the two are often seen talking in corners together at functions.

Russell had the girls laughing with his slightly inappropriate table antics – after all he is a comedian!

Katy, Rihanna and Taylor also pulled Black Eyed Pead first lady Fergie in for a quick pose.

These girls have got to be the funniest posse in Hollywood!

Whack or wicked? Lady Gaga's craziest outfits.
