Katy Perry left our mouths watering last week when she gave us a small taste of her "Unconditionally" video, and in just hours, she's going to treat us to the whole thing when the clip premieres tonight (Novmeber 19) at 7:53 p.m. ET on MTV as part of "MTV First: Katy Perry 'Unconditionally.'"

And according to the Prism singer herself, we're in for something a bit more decadent than the clips we're used to from her. Following tonight's premiere, Perry will sit down for an exclusive 30-minute interview with rapper Iggy Azalea on MTV.com to dish on everything "Unconditionally," including what makes it such a departure from her previous music videos.

"It doesn't have a complete narrative. I do that all the time; I usually have quite a big story line.... This time I wanted to give a lot of gorgeous, beautiful looks, which I don't usually go for," she said in a preview of "MTV First." "But it's mostly just a beautiful video that is supposed to evoke this power of love."

In celebration of the upcoming music video premiere, on Tuesday, November 19, AMTV, MTV Hits, MTV's 24-hour U.S. music channel, and mtvU will feature Katy Perry artist collection blocks throughout the day. After its on-air debut, "Unconditionally" will go also into rotation immediately on mtvU, MTV Hits and AMTV the following morning.

Don't miss the premiere of Katy Perry's "Unconditionally" video on Thursday, November 19 at 7:53 p.m. ET on MTV!
