SWEATER WEATHER
Teammates that keep each other's privates warm apparently win Olympic medals together ... 'cause Tom Daley revealed he once gifted his diving partner, Noah Williams, a "c*** sock" before they nabbed silver in Paris on Monday.
Daley actually told his fans about the unique gift way back in January -- some six months before the two teamed up to podium at the men's synchronized 10-meter diving event in France.
The guys were doing a Q and A on YouTube when Daley said the present was a last-minute 21st birthday gift for Williams.
