Ashley Tisdale is officially off the market — the High School Musical star married fiancé Christopher French on Monday! The actress announced the exciting news via Instagram on Tuesday with a gorgeous snap captioned, "Best day of my life! Introducing Mr. and Mrs. French Sept 8, 2014." Ashley and Christopher, a musician, got engaged in August 2013 after nearly eight months of dating. Back in May, Ashley and a group of girlfriends — including her longtime pal Vanessa Hudgens — celebrated her bachelorette party on a yacht in Miami. Vanessa was reportedly on hand for Ashley's nuptials this week as well. Congrats to Christopher and Ashley on their big day!
