Wilmer Valderrama Suffers Through Demi Lovato's Hilarious Skincare Video

Wilmer Valderrama must really love Demi Lovato.

In a cute new video for Demi's own skin care line, "Devonne by Demi," the "Heart Attack" singer adorably tortures her boyfriend Wilmer by using him as a model for all her different products.

But unfortunately for the That '70s Show actor, she isn't exactly using the products sparingly.

"Get your man ready for Valentine's Day with @DevonnebyDemi! #DevonneYourMan," she tweeted about the funny video on Wednesday.

Demi, 22, and Wilmer, 35, first got together in 2010, and reunited after splitting in 2011. Just two weeks ago, Demi took to Instagram to wish her man a happy birthday by posting black-and-white pics of the couple through the years.

"Here's to many more incredible years together," she wrote. "Happy Birthday my love.... I love you ❤️❤️❤️"

ET actually caught up with Demi last October at the Vevo Certified SuperFanFest concert in Los Angeles, when she gushed about her longtime boyfriend.

"Wilmer is one of the most incredible people on the planet," she told ET correspondent Lance Bass.
