Blondes really do have more fun—or so Christina Aguilera assures us.

After spending nearly four months as a fiery redhead, a vibrant hue she debuted back in June while attending a fundraiser for Hillary Clinton, the "Change" singer has switched things up once more and has gone back to her signature hair color: blonde.

Aguilera, who has rocked her tresses in a variety of colors and styles over the years (from hot pink ombre to amber streaks to glossy black), revealed her return as a golden-haired bombshell on Saturday, September 24, sharing a sassy photo of her new, Old Hollywood-inspired hairdo on Instagram.

Back to basics, indeed. See below:

Speaking to E! News, celebrity hairstylist Chris Appleton, who is the stylist behind Xtina's redhead-to-blonde transformation, explained the decision for the style switch, sharing that the pop star is a "true blonde at heart."

"We decided to take Christina back to blonde as it was time for a change. Christina wore the red hair and loved it, but it was time to go back to her roots..." he told the site. "We wanted to create the iconic platinum look so we kept it really nice and bright with a cool tone for a modern finish."

Appleton added, "We styled it in a Rita Haworth style wave to give it that real Hollywood finish."
