Well as the title said I (sadly) completely forgot the singer's name and the name of the song. However I do remember that it was a girl (in my opinion she looks abit like zoey deschanel)and the videoclip is that the girl is at some sort of a party?.

Hi, you don't say how old it is, but Katy Perry looks a bit like Zoey Deschanel, and the video for Last Friday Night is at a party... you can watch it on YouTube, sorry if it's not what you're looking for.
