They both wore similar outfits, but
there was clear distinction between Selena Gomez and Katy Perry at the
Nickeloden Kids' Choice Awards this evening.

The two stars turned up to the children's event in bralets and
miniskirts to walk the red-carpet at the Galen Center at USC in Los
Angeles tonight.

But while
the 19-year-old singer and actress looked elegant in her printed and
bedazzled two-piece, the 27-year-old pop star tried to avoid being slimed by wearing an ensemble resembling the green goo.

The newly single star's top looked like she was dripping in the matter and her skirt also possessed a similar squiggly design.

As well as her bright green clothing, Katy
had also attached a purple and turquoise hair piece ponytail to her already blue
hair.

herself in a black one-shouldered cocktail dress, after the Fashion

well as her violet-grey coloured hair, she added a pop of colour in her
footwear, sporting a pair of hot pink peep toe stilettos.
