Clooney took a new picture of the pup as he added her to his "House of Friends"
Clooney personally added his floppy-eared friend, Millie, to his Casamigos, “House of Friends,” over the holiday.
In a photo, taken by Clooney himself, the 4-year-old pup sits on a rug wearing a Casamigos Tequila baseball cap turned sideways as she gives the camera her best puppy dog eyes.
The Gravity star and his wife Amal Clooney adopted Millie from the San Gabriel Valley Humane Society in October, just weeks after she was found searching for food scraps outside of a local restaurant.
After an hour and a half “meet and greet” with the dog, during which she was introduced to their other rescues, Millie became the newest member of the Clooney clan.
“Millie found her forever home and Clooneys have a new best friend,” Jennifer Clarke, the shelter’s social media coordinator told PEOPLE at the time. “They all left together as one big happy family!”
