She’s made quite a splash all over the world ever since her hit song “I Kissed a Girl” hit the charts earlier this year.  And last night Katy Perry was entertaining the crowd over at the 55th Annual ONDA Awards in Barcelona, Spain.

The “Hot N Cold” songstress arrived at the Liceu Theater looking uncharacteristically formal, sporting a muted lavender strapless gown as she posed for the paparazzi.

Once inside, Miss Perry took to the stage for a rousing rendition of “I Kissed a Girl,” much to the delight of the event’s spectators.

Changing her clothes for the performance, Katy donned a flamenco-style ensemble including vibrant orange gown and a yellow flowery shawl, completing the look with a tightly scraped-back hairdo and a green fan.
