The Grammy nominee, 24, and the MMA fighter, 31, were first linked last July when an insider told PEOPLE the pair had a “quick fling.”
Lovato — who was named one of Time‘s 100 Most Influential People of 2017 and announced Monday morning she’s teaming up with Fabletics to create a capsule collection that reinforces female empowerment and body positivity — briefly dated UFC fighter Luke Rockhold afterwards, but rekindled her romance with Vasconcelos after they split.
“It wasn’t a dramatic split,” says the source. “Bomba is a good guy, but the relationship just ran its course.”
Over the last few months, the “No Promises” singer and the fighter — who rang in the New Year together — made their relationship social-media official, posting cute photos of each other on their Instagram accounts.
Vasconcelos most recently shared a photo of them on April 17, captioning the snap “I miss you soo much!”
In April, Lovato — who’s also busy gearing up for the release of her YouTube documentary, I Am: Demi Lovato, later this year — gushed about Vasconcelos during her appearance on The Ellen DeGeneres Show, telling the host “Isn’t he cute? He’s so cute! I’m very happy. Life is really good.”
A rep for Lovato could not be reached for comment.
