Fans definitely thought they were the real deal and now we have even more evidence that Demi is totally head over heels for this guy! There's no telling when Demi is going to publicly announce that she's dating Guilherme, but to be honest, she doesn't really need to.
Guilherme posted another photo of them hugging, showing off those soft smiles and just looking like a downright couple! He's an MMA fighter, which means he's super strong.
A pre-fame Lovato dated a boy named Jonathan Fryar in 2007.
A picture that surfaced later led to rumors that she’s dating fellow Disney alum and Sky High actor, Nick Braun. Her first confirmed relationship was with Cody Linley, who played the on-screen love interest of Miley Cyrus on Hannah Montana.
Linley told Seventeen that he had his worst date ever with Demi. It was a series of unfortunate events starting with Linley picking her up two hours late because of an audition that ran behind and his car broke down.
He had more car troubles when they were driving to a restaurant.
Cut to 2010, however, and Gomez and Lovato no longer seem to be close friends.
