How does the son of a couple rock stars spend the Christmas holiday? Learning to roller skate!

Gwen Stefani and Gavin Rossdale took their eldest son Kingston, 2, to Moonlight Rollerway in Glendale on Dec. 23 for an afternoon on wheels.

"It looked like it was Kingston's first time roller skating, and the little guy looked so cute," an eyewitness said. "Kingston tried to skate between Gwen and Gavin, but even though they were holding his hands, Kingston's legs kept skating in different directions so it was impossible for him to stand up."

The tot was all laughs despite his efforts, and managed to stay upright to dance the "Hokey Pokey" with his mom.

The following day, the whole Rossdale family – including new addition Zuma – attended Christmas Eve Service at St. Charles Borromeo Catholic Church in Los Angeles.
