Becoming a princess is hard work!

With her April 29 wedding to Prince William just around the corner, Kate Middleton is a busy lady primping and prepping for the big day! Middleton, 29, is keeping her skin perfect with her favorite oxygen-charged skin cream, and she's stealthily getting her hair and nails done at the Richard Ward salon.

The soon-to-be royal should have already sent out her estimated 1,800 wedding invitations--including one to David and Victoria Beckham. The official menu remains top-secret, but if Middleton needs some comfort food, she can nosh on her favorite 805-calorie burger from the Ebury Brasserie, conveniently just around the corner from Buckingham Palace.

An insider tells UsMagazine.com: "There is still so much to organize and sign-off… Kate's started to feel a little nervous. Time is ticking!"
