Katy Perry To Premiere 'Part Of Me' Video On 'MTV First'

Singer will chat for 30 minutes after premiere on Wednesday, March 21, at 7:23 p.m. ET on MTV and MTV.com.

Katy Perry is ready to give the world "Part of Me." The singer will world-premiere the video for the track during "MTV First: Katy Perry" on Wednesday, March 21, at 7:23 p.m. ET on MTV.

In addition to the video premiere, she will sit down with MTV News' James Montgomery for a 30-minute chat about the video as well as her forthcoming album, Teenage Dream: The Complete Confection (out March 26), and her upcoming concert movie, "Katy Perry: Part of Me." That all takes place on MTV.com.

Perry's fans can get in on the action immediately by submitting video or text questions beginning Thursday (March 15) via Twitter (using @MTVNews / hashtag #MTVFirst or #KatyQ).

Before the premiere of "Part of Me," a tease of the clip will air on "VH1's Big Morning Buzz Live" on March 21 at 10 a.m. ET/PT, giving fans a taste of what they can expect from Katy in the video. In the super-fast teaser, Perry is channeling her inner marine. A few shots of guns and night vision preview boot camp for the singer. The sneak peek closes on Perry's face painted in camouflage makeup. She shot the video on a military base in California in February.

Immediately following the premiere of "Part of Me" on MTV, the video for the deeply emotional single will air on Logo, debut on MTV.com, VH1.com and LOGOtv.com, and go into rotation on mtvU, MTV Hits and AMTV the following morning. Additionally, the video will debut on Saturday, March 24, at 9 a.m. ET/PT during VH1's "Top 20 Countdown" and on TeenNick's "Obsess This" music block at 7 a.m. ET and Sunday, March 25, at 8:30 a.m. ET.

This is hardly the first time that Perry has gotten the "First" treatment. In 2011, she sat down with Sway Calloway to premiere her trippy Floria Sigismondi-directed video for her chart-topping Teenage Dream single "E.T." She later won the Best Collaboration VMA with Kanye West for the video.
