Lady Gaga, Taylor Kinney have Wild West night

Whoa!

Lady Gaga hit the slopes of Park City, Utah, this weekend for Operation Smile.

A week after the music superstar and her fiance, Chicago Fire actor Taylor Kinney, took a dip in frigid waters for the Windy City's 16th Annual Polar Bear Plunge for charity, the hot couple were heating things up out West at another benefit.

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

The couple arrived Saturday night at restaurant Tupelo in Park City to show their support, and her ensemble appeared to be a nod to the Wild West.

She wore a Max Mara camel jumpsuit with wide-brimmed cowboy hat and he wore a red and black plaid flannel shirt. Cute!

His brother, Trent, was there and the trio were snapped together at arrivals.

Once inside, Gaga spent time with Ashlee Simpson-Ross.

In a video post on Instagram, it seems like the night was long but ended on a sweet note as Gaga played the keyboard while Kinney held on to his lady love.

Awe.

But to prove that she really did hit the slopes during the weekend, Gaga shared a pic Sunday of her and DJ White Shadow outdoors with snowboards.
