Zac Efron and Nina Dobrev appear to be all smiles while vacationing with friends in Italy. On Saturday, September 20, Deux Moi shared photos of Efron, 37, and Dobrev, 36, onboard a yacht, alongside Chase Crawford and Miles Teller and Kaleigh Teller. In one photo, the floral-dress-clad Vampire Diaries star looked especially cozy as she and Efron, sporting a white backwards cap and white button-up shirt, appeared to talk about something on her phone. In another photo, both Efron and Debrov could be seen laughing together while facing forward.
