Haylie and Hilary Duff at the Runway For Life Event to benefit St Jude Children’s Research Hospital, held at the Beverly Hilton Hotel, Los Angeles. 11th October 2008.

Haylie Duff has found love with a former flame — Nick Zano! Hilary’s big sis, who recently split from actor Charlie McDowell, rekindled her relationship with Nick, the ex of Kristin Cavallari, on a romantic getaway to the tropical island of St. Maarten over New Year’s. “Haylie started dating Nick a few weeks after her breakup. She didn’t waste any time,” says a pal of Haylie’s. Nick and Haylie, 22, dated before the What I Like About You actor started seeing Kristin in 2006.

It looks like they had fun building sand castles and posing for the paps.
