Jesinta Campbell debuts dramatic platinum makeover: 'New 'do'

Hair today, gone tomorrow!

Jesinta Campbell took to Instagram on November 30 to debut her lighter, edgier locks. The 26-year-old model appeared to cut several inches of her brunette mane to a chin-grazing style and added a fresh wash of platinum blonde.

"New 'do," she captioned a photo of herself on the red carpet at the Tiffany & Co "Tiffany" Fragrance Launch in Sydney earlier that evening.

She paired the look with a cropped, off-the shoulder top that showed off her toned abs and pale yellow, wide-legged trousers featuring a stylish silver buckle on the waist. White, open-toe sandals and a quirky taupe handbag completed the look.

"A young Sharon Stone," one follower commented of the cut and colour, which has been the Hollywood actress' signature since the 1990s.

Jet-setter Campbell is back in Sydney after vacationing in Phuket, Thailand, in late November.
