Brandon Davis swimsuit bathing suit bare chested shirtless surf ocean beach waves swimming dip camouflage greasy grandson oil tycoon barefoot

You may not know Brandon Davis outside of his famous "Firecrotch" rant against Lindsay Lohan or as anything other than Paris Hilton's BFF, but the guy's a veritable billionaire!

The oil heir has been, in recent years, rather greasy, rather sweaty when he leaves nightclubs, and often out-of-work and smoking too much ... so is it odd that we think he actually looks kinda hot in these pix???

The Hollywood bad boy was out on the beach in Malibu and we've gotta say -- he's dropped a few pounds, toned up, and the salt water does something cool to his hair. If the thing with Todd Phillips doesn't work out, maybe Paris should just date Brandon!
