Hey M Girls!

We had a blast hanging out in Washington, D.C. at the Worldwide Day of Play -- we caught up with stars like Big Time Rush and the cast of Victorious, watched BTR perform on stage, and laughed on the sidelines while all the Nickelodeon cast members battled on the obstacle course!

Victorious' Daniella Monet was on the Black Team and she went around to all the fans getting them to chant their support for her team.

And tons of athletes like Carmelo Anthony, Dwyane Wade, and Abby Wambach were there to coach the teams -- here's a pic of Jennette greeting LeBron James!

Can you see who's in the giant soccer balls? LOL

We were loving Big Time Rush's performances on stage, too! Here's a clip of them singing "Boyfriend!"

And BTR took it a little slower with "Worldwide" -- watch the clip below:

But we have to admit, we loved "Big Time" the best because James AND Logan both do flips! Check them out below:

So let's dish: - Did you participate in the Worldwide Day of Play? If you could meet any Nickelodeon stars, who would you want to meet?
