Scarlett Johansson's Gorgeous 'Late Night With Jimmy Fallon' Appearance

Scarlett Johansson has been rocking some gorgeous looks lately while promoting her new film, "Don Jon."

She wowed in a little black dress during the Toronto International Film Festival, stunned in a sea-green frock at the New York premiere and then stepped out in a skintight Catherine Deane dress for an appearance on "Late Night with Jimmy Fallon" last night (Sept. 13).

Johansson, 28, recently got engaged to her boyfriend of almost a year, Romain Dauriac, and she displayed her art-deco diamond ring while chatting with Fallon about her busy month.

The actress admitted that her grandma loves to buy magazines and tends to reiterate the tabloid stories over the phone.

"She called me and told me a couple of months ago, 'I am so happy Bubee, you adopted a baby!' I was like ... 'I am not adopting a baby,' and she's like, 'Yes you are!'"

Too funny!
