Yesterday we snapped the always adorable Harlow and Sparrow Madden with their nanny, and a little bit later all sorts of famous faces (including Ellen Pompeo!) showed up to celebrate the celebritot's first birthday. Sparrow, who was rocking a mighty cute baby 'hawk, turns one on September 9, but with the holiday weekend and all, Saturday seemed like the perfect day to throw a bash.

We caught hot daddy Joel Madden welcoming guests outside, and we even got a peek at Uncle Benji too!
