Why's Leo Screaming?

Leonardo DiCaprioCrikey, what's Leonardo DiCaprio up to?

Giving his lungs a good airing out, that's what.

And the facial gymnastics were all in the name of fun, or something like it.

Hunky Leo indulged his inner adrenalin junkie and hopped on a hair-raising roller-coaster ride with pals in California.

And no, he's not screaming at anyone.

But rather he looks like he's screaming in delight. Or fright.

We prefer our tootsies firmly planted, thank you.

So we'll leave the scary loops to brave types like Leo - wonder if he's humming Ronan's Life Is A Roller Coaster in his head...
