Will, Kate hit red carpet for 'African Cats'

Umbrellas up! It's a soggy day in London, but that didn't stop our favorite royals from stepping out for a good cause.

Prince William and wife Kate have been fairly low profile ever since Wills returned from the Falklands on March 21.

But the Duke and Duchess of Cambridge are hitting the red carpet now in London for the U.K. premiere of African Cats, a Disney documentary that follows a pride of lions and a family of cheetahs.

(Will's hair looks fuller and darker to us. Did he pay a visit to a special salon?)

Held at BFI Southbank in London, the screening is set to raise funds for U.K.-based conservation charity Tusk Trust.

The royal duo will be celebrating their one-year anniversary on Sunday (April 29), and a St. James's Palace spokesman has confirmed they'll be doing that in a low-key way as well -- spending it privately.
