Our photog caught the Australian pop star and a buddy early Wednesday morn on the Sunset Strip, and asked about Selena's IG of them all enjoying cones and cream together.
Check it out ... Cody tried to shut down any rebound rumors by claiming he and his friend are "no f**k boys." Google it if you don't know it, but basically ... he ain't trying to bang her. Or so he says.
His ex, Gigi Hadid, and Joe Jonas also came up ... and we're now 100% positive a Simpson-Jonas collabo will not be happening any time soon. Mostly though, this 2 AM-ish video is proof Cody and co. had a strong night at the bars!
Ahh, the single life.
