Remember those whispers about a duet between Christina Aguilera and Demi Lovato? Well, they are slowly and surely picking up, especially after budding singer Jon Bellion confirmed that he was the producer behind the forthcoming collaboration via a now-deleted message on Twitter.

On Tuesday (April 3), Bellion replied to a tweet (that he wasn’t even mentioned in) about how Lovato recently quoted a lyric from the reported duet at hand (“Fall In Line”) and responded, “Its not supposed. I produced it,” along with the laughing emoji. Thankfully, nothing ever leaves the Internet permanently and a sneaky user on Twitter captured the message before it was gone. Bellion might not be a household name, but he’s one of the many collaborators behind a couple of notable hits, including Eminem and Rihanna’s “The Monster” as well as Jason Derulo’s “Trumpets.”

This is the latest update on the secret that keeps on surfacing. During a concert in March, Lovato spoke highly about Aguilera, telling the audience “Now Christina’s my girl and big things are coming.” It’s a line that echoes the very same quote that Aguilera said about Lovato when the pop vet was caught out and about by the paparazzi.

In our previous interview with Lovato, the singer shared some high praise for Xtina’s blockbuster 2002 LP, Stripped, and how much it inspired her most recent album, Tell Me You Love Me. “What I find inspiration from in the Stripped album was the soulfulness of Christina’s voice,” Lovato said. “It also was her coming out album, where she was just sexier, and more grownup, more mature, and I feel like that’s what this album is for me.”
