We've watched the preview of Katy Perry's "Part Of Me" video approximately 89 times, so apologies in advance to all my friends and family who won't be able to get me out of my Katy Perry black hole after I watch the full-length video tonight, premiering on MTV at 7:23 p.m. ET. Going for a record of 150 consecutive viewings. Wish me luck.

The best part: After "Part Of Me" premieres and you're Kristin Wiig-ing in your room, keep the mascara running during "MTV First: Katy Perry." KP sat down with MTV News' James Montgomery to chat about global warming, the upcoming election and universal health care. JK, they talked about fun stuff like Katy's crazy famous life and her music. She even answered fan questions. (Fingers crossed she accepted my proposal to be pen pals.)
