Alec Baldwin -- Schweaty Balls?

8/6/2007 3:25 PM PDT
It must have been a hot weekend in the Hamptons -- as Alec Baldwin got all soggy in a button down shirt. Profuse perspiration or an impromptu wet t-shirt contest? Either way, not good.

TMZ cameras were at a Billy Joel concert on Saturday, where Baldwin left the venue dripping -- in what appears to be sweat. Baldwin even had to pick up a nice dry t-shirt on the way out the door, proudly showing it off to our photog.

Cameras spotted Alec at the American Hotel later that night, sporting the same, but less wet, sweat shirt.
