The star running back just tweeted, "I don't think I've ever not peed in the hot tub."
Warning to Arian Foster's teammates -- he's not afraid to piss all over you if you dare to get in the hot tub with him.
Not that anyone asked, but Foster's confession is definitely news his buddies on the Houston Texans can use during training camp.
Foster went on to explain, "If you go in having any prior liquids in you, and dip your whole body into warm liquid relaxing every muscle, it's inevitable."
We smell a ploy to get the hot tub all to himself.
