While all eyes were on Kate Middleton and Prince William today at Westminster Abbey, it was hard not to also notice how charming the children in attendance looked. Middleton's sister Pippa led the bridal party down the aisle, which included seven-year-old Lady Louise Windsor, and the Honorable Margarita Armstrong-Jones, 8, shown. William Lowther-Pinkerton, 10, helped the girls out of the car before their big entrance. Adorable!
