The newly-engaged duo took part in Chicago's Polar Plunge on Sunday, jumping into icy Lake Michigan in an effort to raise money for Special Olympics.
Braving the 31 degree weather, Mother Monster, her shirtless beau, the actor's "Chicago Fire" costars and even Vince Vaughn dove into the freezing cold water.
Gaga took to Instagram to share some snapshots from the plunge, writing, "Feels so good to do things for a good cause like the Special Olympics. It's great donate money, but also great to donate a gesture of love for those who deserve to be showered with it."
In the pics, Taylor's super-toned abs were on display as he carried his fiance on the beach and goofed around with pals. One thing that didn't fare too well though was the singer's hair!
"My weave froze!! Taylor gave me his hat I thought my wig was gonna freeze into and become one with the lake," she wrote along with another pic.
Now that they've taken the Polar Plunge, it's time to get hitched and take the leap into marriage!
