How does rockin' mom Gwen Stefani spend her holiday season? By hitting the sloped in Mammoth, Calif. with her equally hip son Kingston, of course!

The mom of three grabbed a pair of skis and pulled on some oh-so-stylish all-white snow bunny winter gear and headed to the mountains with her family on Monday.

Gwen and Kingston looked like they were having some major bonding time as they enjoyed some time together off the slopes. They were later joined by big papa Gavin Rossdale.

Instead of going for his mom's monochromatic look, Gavin and Gwen's first born opted for a colorful creation for his romp in the snow.

Later in the day, Kingston joined his little bro Zuma for a bit of fun-filled sledding. Sounds like a fun vacation if you ask us!
