A newly revealed as pregnant Hilary Duff and her husband, Mike Comrie, double dated with her sister, Haylie, and boyfriend Nick Zano at LA's Sushi Yuzu last night. It was a momentous weekend for Hilary, who announced her pregnancy on the eve of her first anniversary with Mike. It was just 12 months ago when Hilary walked down the aisle wearing a Vera Wang gown in front of 100 of their loved ones, and now the couple are preparing to tackle a new chapter together. Last month Hilary and Mike got a jump on their anniversary celebrations with a bikini-filled getaway to Italy. It's been an exciting 24 hours for the parents-to-be, and Hilary reached out to fans over Twitter thanking them for the outpouring of support and love, saying, "Wow! I am just overwhelmed by all of the wonderful messages everyone is sending! Thank you so much! Big hugs! Xxo."
