J-14 just hung out with Degrassi's Melinda Shankar (she plays Alli) and Sam Earle (KC)! The two flew down to New York City from Toronto for Nickelodeon's World Wide Day of Play. Nick is shutting off their programming from noon until 3 p.m. to encourage everyone to get outside!

To celebrate, Sean Kingston will be performing, and Melinda and Sam get to introduce him to the crowd. "I am so excited to meet Sean because I hear he's really nice!" Melinda tells J-14.

They may be TV stars, but Melinda and Sam enjoy spending time being active, too. "Since I was 3, I've been doing ballet and karate. I know it sounds like an awful mix, but somehow they help each other out! That's how I get out there and active," Melinda reveals. And Sam loves sports too -- he's played hockey since he was a kid, and he shocked Melinda by revealing that he took dance lessons as a little kid, too!

They're not the only stars getting in on the action -- Victoria Justice and True Jackson, VP's Keke Palmer are so excited for tomorrow that they also made an exclusive video just for J-14!

What do you do to get active? Will you be shutting off your TV tomorrow?
