Lady Gaga got cold for a good cause earlier today.

Gaga, along with her fiancé Taylor Kinney, took part in the Chicago Polar Plunge to benefit the Special Olympics. In a video too short to justify embedding here, Gaga can be seen piggybacking on the shoulders of her husband-to-be as the marched into the freezing waters of Lake Michigan.

Joining Kinney and Gaga was NBC's Al Roker, who took questions with the couple preceding their plunge. 

It was the second straight year that Gaga has participated in the event, and she assured that her and her soon-to-be hubby would be there for years to come.
