Penn Badgley's Twitter avatar is a photo of Cardi B, and Cardi B's is a photo of Badgley's much maligned You character Joe Goldberg.

Their friendship formed in real-time on Twitter earlier this month:

That led to Netflix's official Twitter account changing its bio to say, "Petition to get Cardi B to guest star in Season 4 of You!" And, of course, Cardi stoked that fire:

So it’s episode 1 and I’m at Paris Fashion week shutting it down! I turn around and there stands YOU

Badgley, 34, addressed all of this while visiting Jimmy Kimmel Live on Monday, stating "I don't know" repeatedly when Kimmel pressed as to whether the diamond-certified, Grammy-winning rapper will invade his You world.

"I definitely can't say, but there is actually—I believe this is true—there's an actual Change.org petition," he added, noting that he wasn't trying to be "coy" and actually doesn't have any idea.

The former Gossip Girl star was correct. That petition can be viewed (or signed) here.

You premiered its third season on Oct. 15 and was renewed for a fourth before it even began streaming. The psychological crime drama debuted in September 2018.
