Ariana Grande is celebrating one year of being blonde!

The singer, 30, marked the anniversary with a post on her Instagram Story Friday, in which she shared a behind-the-scenes look at the October 2022 hair transformation.

“Happy [one] year blondieversary,” Grande wrote over a mid-bleach mirror selfie with foils in her hair.

The “Positions” songstress also adorned the post with several blonde, ponytail-wearing emojis.

Elsewhere in the post, Grande tagged Francesco De Chiara, the London-based hair colorist who first lightened her hair last fall. He could be seen in the picture applying bleach to her then-brunette tresses.

The “Side to Side” singer also shared another pre-blonde throwback photo, a selfie dated Oct. 21, 2022, which she captioned, “Before @frankhaircolour.”

Grande debuted her hair transformation in an Instagram post last year. Alongside a side-profile selfie — in which she sported her new blonde locks — the actress cheekily wrote, “new earrings.”

From her Victorious character’s cherry-red locks to her signature high pony, Grande’s hair has always been a highlight of the musician’s looks. And while her 2022 color switch wasn’t the first time she went blonde (see her 2018 platinum era), it was a significant change.

The r.e.m. beauty founder adopted the honey-blonde look for her latest role — Glinda the Good Witch in Wicked.

Director Jon M. Chu first announced that Grande would be stepping into the character’s iconic shoes in November 2021. She is set to star in the film adaptation of the Tony Award-winning Broadway musical alongside Cynthia Erivo as Elphaba.

The “7 Rings” singer has since been spotted rocking her blonde tresses on the Wicked set in Buckingham, England, several times, both solo in full Glinda garb, and alongside costars like pal Jonathan Bailey.

The musician also sported the look at Wimbledon with Bailey, 35, during a London shopping outing with Erivo, 36, and, most recently while watching a performance of the Broadway musical & Juliet, which features two of her songs: “Problem” and “Break Free.”

Wicked, which was “only a few days away from being done” before the SAG-AFTRA strike began in July, is currently on pause, and Grande has previously said that she will not be working on any new music until her time as the blonde witch has come to an end.

In a video shared to r.e.m. beauty’s YouTube channel in May 2022, the pop star fielded questions from fans, including one about a follow-up to her 2020 album Positions.

“This is a question I’m nervous to answer, but I feel like I want to have a little bit of transparency and honesty with my fans,” said Grande in response to a fan inquiry about her next record. “The truth is, I have not begun an album.”

She continued, “I hear through the grapevine that you have a lot of theories and expectations in that department. But after Positions, [I] was not ready to start another album yet, so I have not begun another album.”

Grande went on to say that playing Glinda — which she called “the most incredible gift of my entire life” — will “have every piece of me, every minute, every ounce of my heart, my time, my soul, my everything that I can give it.”

“I’m spending all of my time with Glinda,” she added.
