It's not the first time Lady Gaga's gotten dunked in a freezing cold Lake Michigan by her fiancé and hopefully it won't be her last.

Gaga and her betrothed took part in the annual Polar Plunge in Chicago for the second year in a row this weekend, raising money for the Special Olympics alongside Kinney and other celebs (although she really was the main attraction).

In the midst of a media scrum (and dressed down for her) Gaga expressed her excitement at being involved, joking with others involved and generally being quite chipper about the prospect of getting dunked in freezing cold water.

You can see footage of Gaga and Kinney actually taking the plunge below.
