Hilary Duff gave her fans chills when she debuted her comeback earlier this year. Now, just days into releasing her first album in a decade, the pop star is grieving the loss of a dear person from her childhood. On Monday (Feb. 23), she shared two throwback photos and a caption honoring Robert Carradine. Fans of Disney in the 2000s will remember him as her TV dad on the hit show, 'Lizzie McGuire.' Carradine's family confirmed on Monday that he died at age 71.
