When you've been all over the world like these kids have, a bunch of fake dino's in some tar does little to impress.
So it was no wonder Gwen Stefani and Gavin Rossdale's rambunctious twosome looked beyond bored, while on an outing with the nanny at the La Brea Tar Pits in LA ,on Sunday.
Kingston sported his trademark mohawk and a vintage Billy Joel tee shirt, while his lil' bro Zuma rocked a bulky blue cast, rock star shades and adorable fedora hat.
Two-year-old Zuma spent a good portion of his time taking an important call on his iPhone 4, while his five-year-old bro tried to distracted him with kisses.
But the day wasn't a total bore. Both boys fell under the spell of a performing street musician, who captured their interest so long they gave the man a sweet tip. There's no mistaking these kids' parents are in the music industry!
