But this is what she looked like this Sunday, after taking a dip in the freezing waters of Lake Michigan in Chicago as part of the Polar Plunge, raising money for the Special Olympics.
Before taking the plunge with fiancéTaylor Kinney, Gaga didn't look too happy...
Luckily, Taylor was there to give her a piggyback ride/take his shirt off.
As the pair entered the water, Gaga could be seen holding her nose/regretting the decision.
COLD!
Time for some horseplay in the freezing waters...
HER HAIR HAS ICE IN IT.
Bravo, Gaga. Now would somebody please get her a hot drink and a new wig?
