Wilmer Valderrama took to Instagram to prove what many fans already speculated: his pop star girlfriend Demi Lovato is absolutely stunning even when she's sleeping! The actor posted an adorable sleeping selfie of Lovato and shared a sweet, supportive message about her latest album, People reported.

"It must be EXHAUSTING to be that #Confident," the 35-year-old actor wrote in his Instagram caption. "This lil angel created an inspirational & emotional journey.. Then she sprinkled bad ass dust on it! GO GET #ConfidentOniTunes! https://smarturl.it/dlca1 Oh and.. Demi? #Payback hahaha"

Valderrama had a mischievous smirk on his face in the sweet selfie. He looked directly into the camera as Lovato, 22, had her eyes closed with no makeup on, the side of her face buried in a white pillow as she cuddled up next to her man. The "That 70s Show" star proved that he's a supportive boyfriend by promoting his girlfriend's newly released album, "Confident," along with the candid shot.

Lovato has been hard at work promoting her new album, which included a recent performance on "Saturday Night Live" where the former Disney star wowed the audience with her powerhouse voice, according to Vanity Fair. She received many compliments following her performance of "Stone Cold," one of the seven songs Lovato co-wrote for "Confident."
