Jessica Chastain is debuting a dramatic new hairstyle for the first time in years.
The 49-year-old Oscar-winning actress sported a sleek, chin-length bob as she stepped out at the annual Breakthrough Prize ceremony on Saturday, April 18, in Santa Monica, California. The following morning, she made the transformation Instagram official with a short video showing her before and after longtime hairstylist Renato Campora rid her of her long, red locks.
“Choppity chop,” she captioned the post.

Though “The Eyes of Tammy Faye” leading lady is known for her longer hairstyles, she has undergone a few transformations in her past, including in 2018 – a year after she married Gian Luca Passi de Preposulo – when she trimmed her hair to above shoulder length while promoting her film “Woman Walks Ahead,” loosely based on the story of painter Caroline Weldon.
Campora was also behind that hairstyle, which he described at the time as a chin-length layered bob.
One of Chastain’s shortest cuts to date was in 2012, when she stepped out with an asymmetrical bob to film “The Disappearance of Eleanor Rigby” with James McAvoy.
Chastain was just one of the attendees at the star-studded celebration, known as the “Oscars of Science,” that awards $3 million prizes to the top achievements in math and science, while also recognizing up-and-coming talent.
Gigi Hadid, Anne Hathaway, Robert Downey Jr., Michelle Yeoh, Octavia Spencer, Salma Hayek Pinault, Oscar Isaac and Lionel Richie were among the other celebrities in attendance at the event.
