Scarlett Johansson and Colin Jost may never become a serious couple, but there's already a nauseatingly perfect nickname waiting for them: ScarJost.

Johansson brought her Ivanka Trump impression back to "Saturday Night Live" for the May 20 season finale cold open, and stayed for the big afterparty. That's when she reportedly hit it off with "Weekend Update" co-anchor Colin Jost, for some very visible PDA.

"Multiple sources" confirmed the hookup to Page Six:

A witness told Page Six, "Scarlett and Colin were making out at the bar at the 'SNL' season finale party at 30 Rock . . . They would make out a bit, then go back to talking," says the source. "They were at the bar in front of everyone . . . they made out at least twice . . . Then they went back to talking and hanging with other people."

Another source confirmed, "Scarlett and Colin were flirting and canoodling in full view of everyone at the afterparty, including the 'SNL' cast and crew. They were laughing and seemed to really hit it off."

You know you should mind your own business when you find yourself staring at another couple kissing and later report "canoodling" to a gossip site. Anyway, they are both apparently single, so why not? Johansson filed for divorce from her husband in March, and Jost ... wait a minute. What happened to the fake love story of Colin Jost and SNL's Leslie Jones? Is he cheating on her now? That was one response from the always-ready Internet:

And here's a great analysis (not like this hookup needed one, but still) from LaineyGossip:

"Scarjo joined the SNL 5-Timers Club just this year. So she's familiar with the environment, I can see how she'd be comfortable enough to be givin'er out in the open, leaning into her attraction. I mean I don't get the attraction (a man with weak lips has never done it for me and also he looks like Seth McFarlane) but I can see the attraction for Scarjo. It's been five months since she announced her divorce. And she would be into the Colin Jost resumé, that breed of Harvard comedy writer, just as he would be into her – Scarjo is the ultimate dream girl, for almost everyone but in particular for the Harvard comedy writer who has to pretend he's too smart to just want a bombshell model when, really, he just wants a bombshell model. Scarjo is a bombshell but presents as MORE than a bombshell. And so... it's actually perfect. So perfect I can't believe we didn't think of it until now."

Before divorcing her French husband Romain Dauriac, Johansson was married to Ryan Reynolds from 2008-2011.
