Ben Roethlisberger -- BOOZING at Texas Piano Bar

[HAMILROCK]

Ben Roethlisberger is paying extra special attention to his diet this week -- because when he was pounding drinks at a Texas bar Tuesday night ... he wanted his rum mixed with DIET COKE.

TMZ has obtained FOOTAGE of the Pittsburgh Steelers quarterback hanging out at Pete's Dueling Piano Bar in Fort Worth Texas ... where he sang his face off from 11:00 PM until 1:15 AM the next morning.

Sources inside the bar tell us Big Ben arrived with two massive teammates -- and bought several rounds of drinks for himself AND the entire bar.

We're told Ben racked up an $800 tab -- and tipped an additional $200. People inside the bar tell us Ben was "nice, fun and took care of everyone."

In the clip, Ben can be seen singing along to the Billy Joel classic "Piano Man" while his teammates joined in on the fun.

If this was done Saturday night before the super bowl, I would be more concerned. It was a Wednesday night, and last time I checked the game isn't until Sunday. Teammates were there as well, so I wouldn't be too worried if I was a Steelers fan.

Surprised Pittsburgh not favored by -3.5 at least now.
