Haylie and Hilary Duff
Singer, actress and songwriter, Haylie Duff is the older sister of popular actress and singer Hilary Duff. Originally from Houston, both sisters managed to land breakout television roles, Haylie as Sandy Jameson in the WB series "7th Heaven" and Hilary on the Disney Channel's "Lizzie McGuire." These two are close. In fact, they're so close that Haylie was the maid of honor at Hilary's Aug. 15, 2010, wedding to Mike Comrie in Montecito, Calif. Now, that's sisterly solidarity worthy of an honorable mention.
