Scarlett Johansson is sporting some major bling at Comic Con, and it’s not an infinity stone.

The Avengers: Endgame actress recently got engaged to Saturday Night Live co-head writer Colin Jost after two years of dating.

She finally showed off her engagement ring Saturday at the Marvel Studios Panel during the popular San Diego convention.

The panel unveiled the first footage from her long overdue standalone film Black Widow, which also stars David Harbour, Florence Pugh, O.T. Fagbenle and Rachel Weisz.

Johansson took the stage with her co-stars and director Cate Shortland to tease the new installment in the Marvel Cinematic Universe.

She wore a jumpsuit that featured a white top, black pants and a built-in black corset with sheer cutouts that showed off the tattoos on her toned abs.

The Under the Skin star also casually sported a huge rock on her left ring finger.

The 11-carat egg-shaped light brown diamond, which is believed to be the work of Taffin’s James de Givenchy, is estimated to cost around $400,000, according to Page Six.

It’s the first time Johansson has worn the rock in public since accepting Jost’s proposal in May.

The couple first met in 2006 on the set of SNL, when Jost was a writer and Johansson was a celebrity guest host. 

They weren’t romantically linked until over a decade later in 2017, when they were spotted making out at the sketch show’s season finale party.

Jost confirmed their relationship later that year, and the two began walking red carpets together. 

In March, a source close to the couple told People that wedding bells were in their future: ‘Scarlett and Colin are in love and share many of the same interests and the same sense of humor. Scarlett is very happy.’

They added: ‘There is marriage talk with Colin.’ 

The couple first got together shortly after Johansson’s divorce from French journalist Romain Dauriac, with whom she was married from 2014 to 2017 and shares five year old daughter Rose.

Johansson was also married to Deadpool star Ryan Reynolds from 2008 to 2011.
