Demi Lovato And Wilmer Valderrama Are Not Engaged, But They're Still Adorable

Demi Lovato and Wilmer Valderrama might make an adorable duo, but the two are not heading down the aisle quite yet.

Rumors that Lovato and Valderrama had gotten engaged spread after Hollywood Life pointed to a photo of the songstress from Wednesday (Jan. 29) and claimed she was wearing an engagement ring. The website also highlighted a tweet she posted the same day that seemed to hint at something big. (Their story has since been deleted.)

However, the talk was apparently nothing but speculation because Lovato's rep told E! News that she is not engaged.

Still, Lovato and Valderrama are totally cute.

On Thursday (Jan. 30), she uploaded a collage of photos to her Instagram for his 34th birthday. Along with the snapshot, she included a sweet message saying: "To the funniest, most inspiring, incredible man I know.. @WilmerValderrama - thank you for helping me get through my darkest moments.. You truly are a light to this world and to my life.. Happy Birthday!!!"

The "That '70s Show" star responded with a sweet tweet.

Lovato, 21, and Valderrama began dating in 2010. The couple split two years later, only to get back together last February. In December, RadarOnline.com reported he purchased a very special ring for her at Tiffany's over the holidays with the inscription "With you and by you always."
