"Like 8 months ago, that's when we got started."

That's right, Heidi Klum's Internet-breaking transformation into Jessica Rabbit for her 16th annual Halloween party took 8 months to plan, the supermodel revealed last night exclusively to AOL.

The anticipation on the scene at LAVO NYC in Midtown Manhattan was palpable as everyone eagerly awaited Klum's arrival; everyone wanted to see what costume the Queen of Halloween had come up with this year.

Around 10:30 p.m., just after blue curtains had been pulled over the step and repeat and a singular spotlight had been turned on, Klum announced her arrival -- through song. Singing Jessica Rabbit's famous song "Why Don't You Do Right?" from "Who Framed Roger Rabbit?," she sashayed around the red carpet as everyone watching cheered her on. The entire routine was absolute perfection -- surely she had endlessly practiced it, right? Wrong.

"Actually not at all -- because I didn't have this on," Klum said, gesturing to her cartoonishly-large prosthetic breasts, derriére, lips, and eyelids. "I couldn't do a dress rehearsal. I winged it."

When she was asked if it had been difficult to learn the lyrics to the iconic song, Klum was quick to jump to her own defense.

"I sang the song! I went in the studio and recorded the song. It was fun."

Really, Klum was unrecognizable in her get-up. Between the hair, the aforementioned prosthetics, and makeup, she was completely transformed for the night. The question on everyone's minds after the big reveal was, of course, how long it had taken the star to undergo such a metamorphosis.

The answer? Almost eleven hours.

"I started at 12 [noon]. And I literally put my shoes on and got over here at 10:30," she divulged.

"[The hardest part was] holding still," she said. "It's very hard for me to hold still, especially when you have to stand up. When they were doing the face I could sit, but when the body was being glued on I had to stand for hours."

"It was very heavy in the beginning, but now it's fine," she continued. "I got used to it and now I kind of like it!"

We could see why Klum enjoys dressing up for Halloween so much -- she gets such a thrill out of the holiday, and she does an amazing job at commanding the attention during it. She posed with Gigi Hadid on the red carpet and followed Jennifer Lopez into the party, where she made another grand entrance atop the Questlove-manned DJ booth in the basement of LAVO.

When asked if it was hard to learn to move with all of the prosthetics on her body while still looking sexy, Klum continued to have fun and initially answered in character.

"What are you talking about? I do this all naturally," she joked. "No, you know, this booty does it all by itself."

That fake "booty" may have helped her command the red carpet, but it didn't do designer (and former "Project Runway" winner) Christian Siriano any favors when putting the outfit together for her.

"He kind of had to guesstimate," she explained. "We didn't know how the volume would feel on me exactly. He didn't have my proper measurements, so it was kind of hard. I think he kind of stuck [the dress] on a mannequin -- but then the mannequin isn't the real size either, so, it was a make-it-work moment ... we kind of had to glue it on."

And considering how long it takes to put these over-the-top costumes year-after-year, it must take a while to take off after at the end of the night, as well.

"It takes a long time to take off -- probably an hour and a half. I always apologize in advance in case I might be a little tipsy later."

If you ask us, there's no need for Heidi Klum to apologize for anything on Halloween. After all, she owns the night -- and she always makes it work.
