Seven girls will be the belles of the ball at prom this spring thanks to a very special gift from Jessica Simpson. The singer-turned-fashion-mogul popped up on The Oprah Winfrey Show this week, where she paid a visit to students at Father’s H.A.R.B.O.R. Academy in Jacksonville, Fla. The girls’ teacher had written to Winfrey, explaining that several of the students had been in and out of foster care and didn’t have the means to afford a prom look. So Simpson swooped in, outfitting each of the girls for prom — and gifting them all with a full wardrobe from her Jessica Simpson collection. Watch the clip above to see the teens’ emotional reactions, and to check out their gorgeous prom looks!
