Blonde ambition! Billie Eilish bleaches her black-and-green locks platinum as she swaps trademark baggy clothes for tight cardigan

Seven-time Grammy winner Billie Eilish unveiled a dramatic makeover to her captive, combined 157.9M social media following on Wednesday morning.

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

‘Did you guess correctly?’ Billie asked.  ‘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 snug, 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.’

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