Brr! Lady Gaga, Taylor Kinney take (another) icy dip for charity

After taking a dip in Chicago's icy Lake Michigan last year, Lady Gaga and fiancé Taylor Kinney went back into the frigid water for the annual Polar Plunge.

Sunday. Kinney, the Chicago Fire star, bravely faced the cold shirtless. Gaga, meanwhile, had some help.

The event-- which at 40 degrees is slightly warmer this year than it's been in the past-- raises money for the Special Olympics. 

Al Roker and Dylan Dreyer from the Today show were there, too.

Gaga was happy to be a part of the event.
