Prince Harry and Queen Elizabeth Drop the Mic on the Obamas During Hilarious Twitter Trash-Talking

The Royals took on the First Family ahead of the Invictus Games at Walt Disney World.

It's the First Family versus the Royals!

Michelle Obama and Prince Harry have been working hard to bring the Invictus Games -- the Paralympic-style, multi-sport event for service members and vets that Harry created in 2014 -- to Orlando, Florida, on May 8. And what would a competition be without some friendly trash-talking?

"Hey, @KensingtonRoyal! Are you ready for @InvictusOrlando? Game on," FLOTUS tweeted alongside a video of her husband, President Barack Obama, warning Harry to "be careful" what he wishes for.

Harry took over the Kensington Royal Palace account to tweet back, "Wow @FLOTUS and @POTUS, some @weareinvictus fighting talk there! You can dish it out, but can you take it? How on Earth am I going to top that? - H"

Solid emoji use, Prince Harry!

The Royals' secret weapon? An appearance by none other than Queen Elizabeth. "Unfortunately for you @FLOTUS and @POTUS I wasn't alone when you sent me that video," Harry fired back, dropping the mic on the Obamas.

That's exactly how you top that.

Harry recently came face-to-face with a 9-year-old who adorably asked him if he is ever going to be king. Watch the sweet interaction in the video below.
