X17 XCLUSIVE - Britney's Kids At The Zoo!

Britney might not have been able to see her kids today, but it's good to know they had a good afternoon!

Sean Preston and Jayden James spent some fun in the sun at the LA Zoo with K-Fed's nanny and K-Fed's mom - no sign of K-Fed himself, though! Also in tow were Kevin Federline's kids with Shar Jackson, Kori and Kaleb.

Let's hope they all got to pet the giraffes and see the monkeys!
