Julianne Moore is Ariel in "Disney Dream Portrait Series"

For the latest image in the portrait series of celebrities living out their Disney dreams, photographer Annie Leibovitz followed a simple recipe: Just add water.

Continuing the "Disney Dream Portrait Series" that has put stars in all kinds of Disney fantasies, Leibovitz trained her famous lens this time on the undersea world of Ariel, heroine of "The Little Mermaid." To get there, she dressed actress Julianne Moore and American swimming icon Michael Phelps in tails and scales.

The latest Leibovitz photography is part of her acclaimed series as Disney Parks continue, through 2008, the "Year of a Million Dreams" celebration on both coasts.

Said Moore:

"Ariel is my daughter's favorite princess, so I was just really so excited to do it. All the images I've seen that Annie's shot so far – Cinderella and Alice and the prince one – are absolutely exquisite. They are so beautiful and so kind of wonderfully emotional. So I was really thrilled to be asked to work with her and do this."
