Do blondes have more fun?

Kate Beckinsale seems to be seeing if that's the case, as she recently switched up her signature style of long brunette tresses for a dramatic blonde bob hairstyle. The Underworld actress debuted her dramatic transformation at the Roger Vivier holiday dinner on Dec. 6 in Los Angeles.

For the festive event, Kate sleighed in a vibrant red power suit that she paired with a coordinating bustier and sky-high pleaser heels. She also matched her makeup to her outfit, wearing a bright crimson-colored lipstick, courtesy of makeup artist Jose Corella.

And while the 50-year-old donned a statement-making getup, she also made sure all eyes were on her new shoulder-grazing 'do. 

Hairstylist Dimitris Giannetos—who cut, colored and styled the actress' hair— gave Kate voluminous, textured waves and a deep side part. Her bombshell look perfectly complemented her sultry attire.

Before taking the plunge and going blonde, Kate turned heads at Elle's 2023 Women in Hollywood event on Dec. 5 with a glamorous look. She pinned her honey brown locks in a curly updo, which kept the focus on her black long-sleeve dress that featured colorful jewel embellishments and sexy side cutouts.

Of course, Kate's bejeweled look was a subtle version of the epic Titanic-inspired dress she wore to Leonardo DiCaprio's 49th birthday bash last month.

At the time, the Pearl Harbor star stole the spotlight in a little black dress that featured a diamond embellishments on the neckline and a gigantic blue sapphire gem on the waist—which fans compared to the Heart of the Ocean necklace in Leo's iconic 1997 film.
