Katy Perry, Kristen Stewart and Jessica Alba shine at Nickelodeon Kids' Choice Awards

Stars including Jessica Alba, Katy Perry, Selena Gomez and Kristen Stewart pulled out all the fashion stops on Saturday for Nickelodeon's Kids' Choice Awards. The host of glamorous ladies turned out at the USC Galen Center in LA for the annual awards event that honours best of music, film and TV stars.

Katy took to the purple carpet in an eye-catching yellow, blue and black cropped top and matching knee-length skirt. Katy accessorised her outfit with pointed black patent heels and wore her black hair swept to one side.

Twilight actress Kristen also sported a stylish two-piece outfit, matching blue silk t-shirt and shorts by Osman Yousefzada. Kristen marked a year of acting success by being crowned Favourite Actress, although she was covered in the network's famous green slime.

Another lady who attracted attention was Black Eyed Peas singer Fergie, who is pregnant with her first child. Springbreakers actress Selena and Firework singer Katy were snapped in a sweet photo touching Fergie's bump.

Fergie's husband Josh Duhamel was the night's host. The dad-to-be kept the crowd entertained with jokes, singing and dancing.
