Now this is one way to spend a birthday. To ring in Wilmer Valderrama's 36th year, girlfriend Demi Lovato took her longtime love to the Wolf Mountain Sanctuary in Luverne Valley, Calif., on Saturday, where they spent time hanging out with the furry creatures.

But before mingling with the wolves, Lovato took to Instagram to post a handsome photo of her beau, which she captioned with a touching message: "This beautiful man turned 36 today. I thank God every single day that this man came into my life for so many reasons.. But mainly because I'm so blessed to not only have been able to meet such an incredible, loving, funny and inspiring soul, but even more blessed and honored to call him mine. I love you My Wilmer. You deserve the world and more.. Here's to so many more memories Feliz Cumpleanos."

The singer then shared a series of snaps from their day with the wolves, including a selfie with one of the beautiful animals. "Spent the day at Wolf Mountain sanctuary.. It was unbelievable," she wrote. "I fell in love with the wolves there and wish I could spend more time with these beautiful, spiritual creatures."
