Demi Lovato Enlists a Wolfpack to Help Wilmer Valderrama Celebrate His 36th Birthday

By
Demi Lovato and Wilmer Valderrama have extended their wolfpack -- literally.
The From Dusk Til Dawn star rang in his 36th birthday with a trip to a wolf sanctuary in Lucerne Valley, California, on Saturday, and Lovato excitedly documented the wild adventure on Instagram.
"Spent the day at Wolf Mountain sanctuary. It was unbelievable," the 23-year-old singer wrote of the volunteer-run organization, which currently cares for 11 wolves. "I fell in love with the wolves there and wish I could spend more time with these beautiful, spiritual creatures. ❤❤❤."
The visit comes just one month after the couple lost Valderrama's beloved Doberman Pinscher, Spawn.
Lovato posted several pictures of herself and Valderrama getting close to the beautiful canines.

Even Lovato's younger sister, Madison De La Garza, was there to help Valderrama celebrate his big day.

Valderrama also took to Facebook to thank fans for their birthday wishes, writing that he was "so incredibly touched" by the messages sent from around the world.

It's my #Birthday! LolGracias, obrigado & THANKS.. So incredibly touched to be given so much love from AROUND WORLD...
