Who goes to the zoo all dressed up like this?! Gwen Stefani and her beautiful brood, that's who!

Gwen was in full hair and makeup wearing a lovely holiday-inspired outfit at the Los Angeles Zoo in Griffith Park. Gavin was looking hot, as usual, and Kingston and Zuma were in their Sunday's finest ... on Saturday.

After Gavin's been on the road promoting the new Bush album, The Sea of Memories, the couple seems happy to be reunited. They better enjoy their time together, he'll be back on the road after the new year!
