The Tiz is off the market! Ashley Tisdale's boyfriend put a ring on it. Christopher French popped the question in New York City Thursday night, and she said yes! An insider tells Life and Style mag, "It happened on the 103rd floor at the top of the Empire State Building. It was totally romantic and Ashley's over the moon." After the proposal, Ashley tweeted, "Best night of my life. We're on top of the world." The couple has been dating since December.
