The 34-year-old actress smiled and waved for photographers during a photocall with her Avengers: Endgame co-stars, Chris Hemsworth and Paul Rudd, at the Corinthia London in London, England. Johansson wore a Michael Kors long-sleeved floral dress, black tights and ankle boots with a sky-high heel. She pulled the style together with purple eye shadow, a nude lip and a loose up 'do.
The fun and flirty look is a far cry from her fierce ensemble at Wednesday night's premiere for Endgame in London. Johansson hit the red carpet in a black Tom Ford pantsuit that included a cleavage-baring asymmetrical jacket. She paired the style with dangling earrings and a bold gold bracelet, and chose a dark maroon lip color along with a slicked-back hairstyle.
Following the incident, Johansson offered up a warning that if laws don’t change regarding the way photographers pursue celebrities, it could end in tragedy.
"The paparazzi consistently go to increasingly dangerous lengths to stalk and harass the people they are photographing," she said in a statement to ET. "Even after Princess Diana’s tragic death, the laws were never changed to protect targets from the lawless paparazzi. Many paparazzi have criminal pasts and will perform criminal acts to get their shot."
"Yesterday, after leaving the Jimmy Kimmel Show, I was followed by five cars full of men with blacked-out windows who were running red lights and putting other drivers and pedestrians at risk so they could follow me to find out where I was staying and subsequently stalk me and my young daughter for the duration of my stay," she continued.
Johansson concluded her statement with a plea for authorities to be more mindful of such situations.
"Women across the U.S. are stalked, harassed and frightened and a universal law to address stalking must be at the forefront of law enforcement conversations," she declared. "Until paparazzi are considered by the law for the criminal stalkers they are, it’s just a waiting game before another person gets seriously injured or killed, like Princess Diana."
Avengers: Endgame hits theaters in the U.S. on April 25.
