Happy Birthday, Kevin James!

The actor turns 52 years old today — and what better way to celebrate than by taking a look back at the cast of The King of Queens then and now?!

The hit sitcom first hit TV screens everywhere in 1998, and since the comedic series went off the air 10 years ago, we've missed Doug and Carrie Heffernan more than anything!

Throughout the past month, Kevin and his co-star and onscreen wife, Leah Remini, have been reuniting for fun Instagram photos time and time again! So it turns out, Leah will be guest-starring in the finale of Kevin's new show Kevin Can Wait.

"Kevin temporarily goes back to work in the two-part season finale of @kevincanwaitcbs starting May 1st on @cbstv," the 46-year-old actress captioned a photo of the two on the set of his funny show.

Leah previously gushed about how excited she is to be working with her onscreen husband again after all these years. "It's such a joy to be working with my favorite TV hubby ever! For him, maybe not so much? Lol #KevinCanWait," she wrote.

And while we can't wait to see Kevin and Leah back together on TV again, we're still hoping for a reboot of King of Queens very soon!
