Johansson’s publicist Marcel Pariseau told The Associated Press Sunday that the private couple is officially engaged after two years of dating, reports the publication. 

It will be third time lucky for Johansson, 34, who was previously married to actor Ryan Reynolds and journalist Romain Dauriac. 

She shares daughter Rose, who was born in 2014, with Dauriac. 

It will be the first marriage for Jost, who is the co-anchor of SNL’s Weekend Update.

They have kept their relationship on the down-low since first starting dating in July 2017.  

However, the loved-up couple recently sealed their romance publicly when they walked the red carpet together at the premiere of Avengers: Endgame, in which Johansson plays the character of Black Widow.

‘Scarlett says he is different than many of the men she has been with,’ a source previously shared with E! News. 

They added: ‘She is pretty picky who she goes out with even if it’s just dating. They share many similarities together.’ 

A separate insider told the publication that the pair has ‘a good time together.’
