Gavin Rossdale & His Boat Boy

Rockers Gwen Stefani and Gavin Rossdale took their two children - Kingston, 3 1/2, and Zuma, 16 months - for a boat ride in Gustavia, St. Barts on New Year's Day. Zuma looked so content in his daddy's arms as the gorgeous duo docked the boat.

The night before, Gwen rang in the New Year with some famous friends at the private party of Russian billionaire Roman Abramovich. The 40-year-old Don't Speak singer sang an hour-long set to the likes of Lindsay Lohan, Orlando Bloom and his girlfriend Miranda Kerr, Marc Jacobs, Linda Evangelista, and fellow vacationing celeb parent, Jon Bon Jovi.
