It's Hard to Decide Who's Cuter — Zac Efron or His Adorable New Dog

Zac Efron and his girlfriend, Sami Miró, stepped out together in LA on Wednesday. The couple was joined by their newly adopted puppy, who Zac carried in his arms as they made their way down the street. We last spotted the trio out and about over Thanksgiving weekend bringing their adorable little guy to a local pet store. In addition to spending time with his model girlfriend, who he's been dating since September, Zac was also sporting a new mustache. The facial hair could be connected to a project he's working on with Joseph Gordon-Levitt; the Don Jon star shared a photo of himself, along with Zac and director Evan Goldberg, while filming something for his production company HitRECord. Keep reading for more photos of Zac, Sami, and their furry friend, and check out more of the new celebrity couples that came on the scene this year.
