"Feels so good to do things for a good cause like the Special Olympics," Gaga wrote in an Instagram post. "It's great donate money, but also great to donate a gesture of love for those who deserve to be showered with it."

And while Gaga's clothes stayed on during the Polar Plunge, she had some trouble with her tresses! "my weave froze!!" she admitted, but her future hubby was chivalrous even in the cold. "Taylor gave me his hat," wrote Gaga. "I thought my wig was gonna freeze into and become one with the lake..."

The twosome got engaged on Valentine's Day when Taylor, 32, popped the question with the help of a stunning heart-shaped diamond ring.  At the 2015 Oscars, Gaga gushed to E! News she and the Chicago Fire star don't know when they'll be typing the knot, saying, "We're just excited to be engaged!"
