Jessica Biel Goes Blonde With Major Hair Transformation After Met Gala

Jessica Biel is saying bye, bye, bye to her signature brunette locks.

In fact, the 7th Heaven alum is ready to find out if blondes have more fun as she debuted a brand new look in New York City May 9.

Jessica was photographed seen stepping out with long, blonde hair, which was partially covered up with a black baseball cap, paired with a chic black coat and sunglasses.

The new hair comes days after the 42-year-old shut down the red carpet at the 2024 Met Gala—her first met ball in 11 years—as she leaned into the evening's "The Garden of Time" dress code with her watermelon colored silk Tamara Ralph gown featuring a cape embellished with feathers and crystals, and that took over 320 hours to make.

And of course, Jessica had some very specific Met Gala prep—namely, soaking in 20 pounds of Epsom salts the night before.

"30 minute soak night before," she explained in TikTok posted May 6. "[Drink] tons of water then and off to bed early."

"I know some people like to party before Met Ball, and party all weekend and all the things, and I have total respect for that," Jessica added. "This is what I do to get ready for Met Ball."

But her fans weren't the only ones obsessed with her Met Gala fashion as husband Justin Timberlake. The singer—with whom she shares sons Silas, 9, and Phineas, 3—made sure to let everyone know that although he couldn't join his wife on the red carpet because of a concert in San Jose, Jessica's look was taking him to a better place, with him dropping three heart eye emojis in the comments of her May 7 Instagram post showing off her look from the gala.
