I read somewhere that DiCaprio wears a US size 9 hat! That is bigger than mine! Leo is shaped a bit like a lollipop.
I remember Grace Kelly comparisons being made about Jenny Kirk; there was a bit of a resemblance there, and they were both very elegant:
"Once you've skated together long enough, and you're really good friends, you can close your eyes, put your hand out and she's right there." Joe Dolkiewicz, 2011 US Novice Pairs Bronze Medalist
Nancy Kerrigan was compared to Grace Kelly, too:
I would have been here sooner, but the bus kept stopping for other people to get on it. - Sheldon Cooper, The Big Bang Theory
No offense to either lady, but when someone says "Grace Kelly lookalike," Nancy Kerrigan is not the first face that pops to mind.
"Marge, if you're going to get mad at me every time I do something stupid, then I guess I'm just going to have to stop doing stupid things!" - Homer Simpson in the Mr. Plow episode
