Derek Jeter showed off his work-hard, play-hard attitude this week. After the Yankee wowed a crowd at a Morgan Stanley event, he was spotted hanging at the NoMad Hotel’s bar till after 2 a.m Thursday.

A spy said Jeter was imbibing with one male pal and two women when he noticed a group of attractive gals appear at the bar.

“Derek saw they didn’t have enough seats at their table,” said our spy. “So he offered one pretty blonde in the group a chair from his, and brought it over to her.” He also graciously advised the ladies to keep their pretty heads from hitting a stairwell near where they sat.

On Tuesday, Jeter appeared on a panel with Morgan Stanley wealth management honcho Greg Fleming and Harold Ford Jr.
