Ryan O Neal shorts shirt beath

We here at X17online are no strangers to Ryan O'Neal's wild mood swings. The former heartthrob might've yelled "F*ggot, shut up!" at our photog the other day when he said "Hi" to him...

...but now he's just pulling a LiLo on the beaches of Malibu, waving "Hi" back. Yeah, I don't get it either!
