The notoriously private actress, 28, has been keeping her rather dishy French boyfriend, sorry fiancé, under wraps. However a source confirmed to People magazine that, 'They're engaged and very happy.'
The couple walked the red carpet at Venice Film Festival to promote ScarJo's new film Under the Skin, and while Johansson looked stunning in a Versace dress – all eyes were the huge Art Deco sparkler on her ring finger (well, maybe not all eyes). Reportedly, the rock is her engagement ring from a proposal in August.
ScarJo was introduced to Dauriac through a mutual friend, tattoo artist Fuzi (responsible for her recent horseshoe inking), who is the former editor of French underground art magazine Clark and is currently the manager of a creative agency.
Johansson was previously married to Mr Blake Lively, Ryan Reynolds, in 2008 before they divorced in 2011.
The actress said in an interview last year, 'I got married when I was young and it was incredibly romantic and I liked being married, actually. But it is different. It's hard to put into words. To me, being in a functioning relationship doesn't mean you have to be married.'
'I never think about marriage. Is that weird? The only time I ever think about it is when people ask me. It's really not important to me,' she added.
Nothing makes us happier than celebrity weddings. Congratulations!
