Scarlett Johansson and “SNL” comic Colin Jost are secretly playing house — but the setup could cut into ScarJo’s time with her precious baby girl!

“Scarlett wasn’t planning on getting serious so soon, but Colin’s swept her off her feet!” an insider told The National ENQUIRER. “He’s moved a bunch of his stuff into Scarlett’s place, and she’s given him a key.”

As The ENQUIRER revealed, friends warned the 32-year-old “Avengers” hottie against infuriating estranged hubby Romain Dauriac, who reportedly wants custody of their daughter, three-year-old Rose.

“Scarlett’s being coy about how much time she spends with Colin,” added the source. “But Romain’s not stupid, and he’s more than willing to use Scarlett’s evasiveness in a custody battle. Romain thinks it’s irresponsible for Scarlett to have another man around Rose permanently.”

But a spy said Scarlett has already introduced 35-year-old Colin to Rose, adding: “He’s adorable with her! It makes Scarlett weak at the knees!”
