The resemblance between Britney Spears and her two sons is evident when you compare the pop princess' baby picture to Sean Preston and Jayden James when they were little.

Ladies man Leonardo DiCaprio shot to fame relatively young with a recurring role on Growing Pains, but he's almost unrecognizable as a blond tot.
