Obamas, Royals talk trash on Twitter ahead of Invictus Games

With the Invictus Games just days away, the Royal Family and the U.S. president and his wifeare goadingeach other on Twitter, hoping to inspire their compatriots to victory.

The Twitter account of Michelle Obama posted a video addressed to @KensingtonRoyalonFriday morning.

"Hey, Prince Harry," says President BarackObama's wife."Remember when you told us to 'bring it' at the Invictus Games?

"Careful what you wish for," the presidentwarns.

At the end of the video, three Invictus Games competitorsapproachthe camera, doing their best to intimidate their British rival.

Two of them pull frighteningfaces.One of them, though, remains straight-faced and,well, he"drops the bomb."

"Boom," he says, gesturing to the camera.

The video appeared to go over well with followers of @FLOTUS.

And reply they did.Prince Harry tweeted back from the royals' account minutes later.

But it didn't end there.

Harry enlisted his grandmother, the Queen, to prepare a more proper response.

The Queen and Harry are seen watching the Americans'video, but they don't seem too impressed.

"Oh, really," the Queen remarks. "Please."

And,in the video's coup de grce, Harry mocks the bomb-dropping gesture.

"Boom," he says derisively, mugging to the camera.

The Invictus Games are an international athletic event started by Prince Harry for wounded, injured and sick service personnel. They will be held in Orlando, Fla., from May 8 to12.
