The actress showed off her newly-dyed teal tresses (reminiscent of Kylie Jenner's blue ombre locks) via Instagram on Wednesday. Rocking white skinny jeans, a white T-shirt and white pumps, Duff's bright hair definitely stole the spotlight in the candid snap.
"@Ambahhh turned me into a mermaid last night ... love all u girls @riawnacapri @nikkilee901 @ninezeroone xx," she captioned the pretty pic.
The 27-year-old made headlines again earlier this week when she flaunted her fit figure on the photo sharing site. Posing in a black strapless bikini top and matching bottoms, the mother-of-one showed off her rock-hard tummy.
"Hey #moms #westillgotit ❤️ #loveyourbod," she captioned the sexy snap.
The former Disney star has been very vocal in the past about her weight struggles. "I just tell myself, 'I'm 5'2", I'm really fit, killing it in the gym, and doing crazy things,'" she told Elle magazine of her athletic physique. "I love to work out, but I'm just not that concerned with being the skinniest person."
