The 25-year-old spilled the tea on The Ellen Degeneres Show when host Ellen asked: "You're not single right now anymore, right?"
Sam replied: "No, I'm not, which is crazy. "
He added: "It's weird bringing out an album and not being single. Because when I brought out In the Lonely Hour I was so lonely. But now I'm singing songs about another guy."
"I'm quite happy, so it's quite weird."
Last month, the loved up pair were spotted making out in Greenwich Village.
We are SO here for #SAMDON!
Also, kudos to Brandon for finally giving Sam something *happy* to write about (not that we won't miss his ~moody~ tunes).
