Looks like Lady Gaga is a good tipper.
She went out to eat with Michael Polansky in Malibu and they each had separate checks.
On the $44 check a tip of $500 was left and on the check of $17.52 $200.52 was left. Unfortunately whoever left the $200.52 tip did some bad math.
They added $17.52 + $200.52 and got a total of $217.52.
Nonetheless, the serve described Gaga as "cool AF."
