Scarlett Johansson has been very private about her fiance of five months, Saturday Night Live regular Colin Jost. But when at the Elle Women In Hollywood event in Beverly Hills on Monday, the Lucy actress opened up to Extra.

'I'm in a very happy, fulfilling relationship,' the 34-year-old star said about her romance with the comedian. She has been wed twice before: to Ryan Reynolds (from 2008 to 2011) and to French journalist Romain Dauriac.

'I learn a lot of stuff from her all the time, but they're mostly factoids about bugs. But kids today are really tuned in. I mean, she's little, she's 5, but she's still innocent and little.'

The idea that balance can be found 'gives you false hope and it makes you feel crazy.' She was also asked to react to Dolly Parton mentioning ScarJo should play her in a movie. 

'Those are big shoes to fill,' Johansson said. 'Or, probably not. They are probably very tiny, dainty, sparkly, fabulous shoes.'

Johansson said that she's 'never found a biopic that I felt compelled to try my hand at,' but said she would be curious 'just for the costumes alone!'
