It's been an active couple of days for Katy Perry: She celebrated her birthday with the help of Russell Brand and Taylor Swift on Saturday (October 24), and today it's possible she celebrated the official "AMTV" premiere of "Starstruckk," the new video from 3OH!3 that features Perry both on the song and in the clip. It's an excellent slice of jittery, dance-infused alt-pop that gets a very nice boost from Perry's presence. The whole clip revolves around a large public fountain and features a handful of slow-motion shots of busty models, but the most eye-catching female is Perry herself, who dances with the 3OH!3 guys while wearing some sort of strange leotard, and changes into a strange pink and black dress for a frolic in the fountain herself.

The men of 3OH!3 are currently on tour in Europe (their next show in the United States is a spot on the KIIS Jingle Ball in Los Angeles in December). Meanwhile, Perry is recovering from her birthday party and also hard at work on her second album, the follow-up to her debut smash One of the Boys. A number of collaborators have come by Perry's recording studio, including Weezer frontman Rivers Cuomo, producer Greg Wells (who worked with Perry on her first album) and songwriter Cathy Dennis (who penned "I Kissed a Girl" and the Jonas Brothers' "Paranoid," among other hits). She'll also be releasing an album commemorating her "MTV Unplugged" performance on November 17, which will feature two new recordings: A Perry original called "Brick by Brick" and a cover of Fountains of Wayne's "Hackensack" (from their 2003 album Welcome Interstate Managers). In the meantime, Perry's performance in "Starstruckk" will keep us well distracted until she surfaces again.
