Jack Antonoff really is a machine that never stops going!
Jack not only does his own stuff with Bleachers, but he's also been a hitmaker for artists like Lorde, St. Vincent, and Taylor Swift!
Now we're to assume he's also working with another female superstar: Lana Del Rey!
Lana took to social media to share a picture of herself and Jack looking pretty dapper, but mostly it looks like the pair are combining their talents for new music!
Hmmm..will Jack be producing her new album or is it something else entirely?
