Demi Lovato celebrated her 22nd birthday with her boyfriend Wilmer Valderrama at Disneyland, where she was spotted wearing a ring on her left hand - is that an engagement ring? Is Demi Lovato engaged to boyfriend Wilmer Valderrama?

The Daily Mail snapped photos of the cute couple enjoying a day at the theme park to celebrate Demi Lovato’s 22nd birthday. We couldn’t help but notice Demi was flashing a ring on her left hand - is this an engagement ring?

We also spotted a similar-looking ring in the sweet Instagram post her boyfriend Wilmer Valderrama dedicated to Demi.

He captioned the photo:" Wishing you happy birthday would never come close to all the inspiring things I wish for your life.. We laugh our asses off.. While we do all we can to better everything around us.. Love you through all."

Valderrama and Demi are wearing matching holiday-themed pajamas and smiling at each other with love in their eyes. Too cute!

As we previously reported, Demi Lovato lashed out at the Daily Beast over an article that claimed her boyfriend, "That 70's Show" star Wilmer Valderrama, is "so culturally irrelevant he relies on the commodification of his young girlfriend's body in order to re-enter the current celebrity conversation." The article was referring to the alleged topless photos of the 21-year-old singer that leaked this past weekend.

Lovato responded by defending her boyfriend Wilmer Valderrama and tweeted at The Daily Beast on April 10: "@thedailybeast such a classy "news site" you are. Writing horrible things about people you know NOTHING about. Get a LIFE you ignorant f***s"

The alleged topless photos of Demi Lovato depict her in bed with 34-year-old Valderrama and were first obtained and posted by Egotastic on April 5. Many are claiming that the woman in the photos share the same tattoos as Lovato.

Wilmer and Demi have been on and off since splitting in January 2012. They were spotted out together on numerous occasions in 2013, sparking rumors that they were dating again.
