Britney Spears & Iggy Azalea's "Pretty Girls" Performance Might Feature A Big "Surprise" — What Could It Be?

Hold on to your butts: According to famed entertainment journalist Robin Leach, Britney Spears and Iggy Azalea are planning a "super surprise" for their debut performance of "Pretty Girls" at the Billboard Music Awards on Sunday, May 17 — and I'm breathless just thinking about the exciting possibilities. After all, "super surprise" could mean just about anything! Leach writes that he got the inside scoop on the pair's much-anticipated performance from "one of Britney's closest confidantes" this past weekend (in other words: this information hasn't been confirmed). The unnamed source reportedly said:

It’s something that’s never been attempted before at an awards show. But if it can be pulled off, people will be talking about it for months.

Apparently, it's not a done deal just yet. The insider allegedly continued:

We’re going to be ready to do it, but we won’t know until 24 hours earlier when we do the camera-blocking rehearsal if its scope and size will actually work for television. Both girls want something really out of the box, adventurous and unique. They are totally up for it and want it to succeed.

"Out of the box," "adventurous," AND "unique"? That's a pretty tall order for a three-minute-long performance! I wonder what Spears and Azalea (supposedly) have up their sleeves? Here are a few totally plausible guesses:

They're Going To Arrive In A Spaceship

I know how silly that sounds, but hear me out: According to USA Today, the "Pretty Girls" music video was inspired by the goofy 1988 sci-fi flick Earth Girls Are Easy , which tells the heartwarming tale of three aliens who travel to Earth in search of true love. Awww. With that little tidbit in mind, it suddenly doesn't seem so unreasonable to think that Spears and Azalea might make their grand entrance by descending from the ceiling in some sort of UFO-like craft, now does it? That's what I thought. Who knows? The stunt could end up becoming just as iconic as Ariana Grande's futuristic (but incredibly slow-moving) bubble chair from the 2014 MTV Europe Music Awards.

Britney Is Going To Sing Live & Iggy Is Going To Say Real Words That Can Actually Be Understood By Human Beings

HA! Well, it'll always be the dream...

Tony Bennett Is Going To Join Them On Stage

Tony Bennett performs at just about every award show these days. I've never seen the 88-year-old artist sing anything other than show tunes and pop standards, so I think it's time for him to spread his wings and show us all what he's really made of! I, for one, would like to see him try out some hard-hitting choreography, too. He must have picked up some moves while working with Lady Gaga, right?

They're Going To Ride In On The Back Of A Brontosaurus

Let's face it: This is the only way Spears and Azalea could possibly top Katy Perry's giant robot tiger from the opening of the 2015 Super Bowl halftime show. Anybody who's anybody knows that brontosauruses are super-friendly herbivores (duh), so it would be totally and completely safe! (Jurassic Park technology is real, correct? We can bring dinos back to life? Never mind, I'll Google it.) Speaking of Perry's halftime show...

Left Shark Is Going To Make A Cameo

He clumsily danced his way into our hearts back in January, and now, he could be preparing to do it all over again. With his soft, plush fins, giant plastic eyes, and mouth full of "razor-sharp" felt teeth, Left Shark truly is just like us. No wonder he's become an international sensation!

(Not to kill the mood or anything, but in the event that Left Shark is unavailable, we should probably all mentally prepare ourselves for the very real possibility that we'll have to settle for an appearance by one of Perry's tragic-looking beach ball pals. Believe me: No one wants that to happen less than I do... but we must be ready for it just in case.)

That's all I got. Be sure to tune in to the 2015 Billboard Music Awards on ABC on Sunday, May 17! I wonder if any of my ridiculous predictions will come true...

(Spoiler alert: Of course not.)
