Blonde ambition! Billie Eilish looks unrecognizable as she bleaches her hair platinum and swaps trademark baggy clothes for a tight cardigan

Seven-time Grammy winner Billie Eilish unveiled a dramatic makeover to her fans on Wednesday, swapping her trademark baggy clothes for a tight sweater and newly-dyed blonde hair. 

After teasing which hair color it might be, the 19-year-old pop star debuted her platinum-blonde locks with a hair flip as Buddy Rich’s 1946 song Dateless Brown played in the video.

‘Did you guess correctly?’ Billie asked her combined 157.9M social media followers.  ‘Pinch me.’

It’s unclear if the bleaching was done by Eilish’s hairstylist Joseph Chase, who appeared in a ‘6:30am call time’ Instastory with Christina Cessna and Nazanin Jafari.

For the past couple years, the World’s a Little Blurry star has rocked raven locks with neon green roots, so the process must have been extensive.

The other big change for Billie was that fact that she wore a tight, preppy beige cardigan emblazoned with the letter ‘G.’ 

Eilish (born O’Connell) normally sticks to her signature baggy, androgynous athleisure attire selected by stylist Samantha Burkhart in order to avoid being ‘sexualized.’

New look? It was unclear if this new direction in the singer's style is here to stay or if it was just for a video

The Everything I Wanted songstress post received glowing comments for her new look from Storm Reid, Sara Sampaio, and Skai Jackson.

On Sunday, Billie and her brother/collaborator Finneas O’Connell took home record of the year and best song written for visual media trophies at the 63rd Annual Grammy Awards.

‘This is really embarrassing for me. Megan [Thee Stallion], girl, I was gonna write a speech about how you deserve this,’ Eilish said accepting record of the year.

‘But then I was like, “There’s no way they’re going to choose me.” I was like, “It’s hers.” You deserve this. You had a year that I think is unstoppable. 

‘You are a queen. I want to cry thinking about how much I love you. You deserve everything in the world, I think about you constantly. You deserve it.’

The 26-year-old Savage rapper had no cause for complaint considering she won three Grammys on Sunday – best new artist, best rap performance, and best rap song.
