Looking positively demure, Jessica Simpson was a special guest at Operation Smile's 25th Anniversary Gala at the Beverly Hilton. Ms. Simpson, who is their International Youth Ambassador, joined their medical mission in Akura, Kenya, where she assisted the volunteer team with medical evaluations for more than 280 children who needed corrective surgery for their facial deformities. Wearing a simple black high-necked sheath (very unlike the Daisy Duke outfit she wore in "Dukes of Hazzard"), Jessica warbled "Amazing Grace" a cappella, and wowed the SRO audience.

Access Hollywood's Billy Bush emceed the show, which featured Tony Award winning actress and recording artist Jennifer Holliday, and America's Got Talent 2006 winner, Bianca Ryan. The 13-year-old artist received the supreme compliment from Simon Cowell (who is not usually laudatory) who stated "Bianca is potentially one of the best singers I ever heard in my life".

Other celebs in attendance included Roma Downey, and hubby, Reality King, Mark Burnett, Producer Robert Zemeckis, and my husband's niece, Lynda and Stewart Resnick, owners of Teleflora, Fiji Water and Pom Wonderful (to name a few).
