Britney Spears Welcomes Special Guest in Concert: Sean Preston!

Sean Preston Federline is pretty much the man. Or the boy. You get the idea.

Britney Spears' adorable five-year-old - fathered by the fertility god Kevin Federline during their marriage - joined the pop star on stage Saturday in Ohio.

Sean waved to the audience, and his pop star mom planted a kiss on his sweet little cheek. It was a very cute moment, even if it was probably way past his bedtime, and brother Jayden James might have felt a little left out.

Check out a brief clip of Sean and Britney below:
