Nothing gets a girl through a breakup quite like Adele!
Demi Lovato knows this all too well, as she took the stage during her Cleveland, Ohio concert on Friday night to cover Adele's "When We Were Young" -- and absolutely killed it!
An eyewitness tells ET that despite the song's sad tone, the 24-year-old singer "was all smiles, and seemed like she was really enjoying herself." Lovato introduced the cover as one of her "all-time favorite songs," saying that she had never performed it live before.
The song was definitely an interesting choice for Lovato, following news of Wilmer Valderrama's rumored romance with Minka Kelly, which she appeared to address on Twitter the day before her performance.
"You have to be capable of being honest with yourself before you can get honest with other people," she wrote on Thursday.
Valderrama and Kelly, who were last linked back in 2012, were spotted having dinner in Hollywood earlier this week, with an eyewitness telling ET they looked like "much more than just friends." According to the eyewitness, Valderrama couldn't keep his hands off Kelly as he "touched her back as they were waiting to be seated." The two arrived and left together, heading back to the former Friday Night Lights star's house after dinner.
"After almost 6 loving and wonderful years together, we have decided to end our relationship," they announced in a joint statement. "This was an incredibly difficult decision for both of us, but we have realized more than anything that we are better as best friends."
