Megan Fox debuted her red hair transformation as she hit the red carpet on Tuesday evening, while wearing a very risqué dress.
The 36-year-old joined her fiancé Machine Gun Kelly as the power couple attended the Time100 Next Gala in New York City, with the rapper named as a Time100 Next honouree.
Megan, who previously had dark brown tresses, showed off her fiery new hair while wearing a figure-hugging gold gown with a dramatic thigh-high split.
The mum-of-three opted for a glamourous makeup look as she wore dark red lipstick and gold smoky eyeshadow. She also added bronzer for a sun-kissed glow.
Megan accessorised her outfit with a small gold clutch bag and gold strappy heels.
Her husband-to-be, 32, rocked a black latex outfit which included a barely-there corset, allowing him to showcase his extensive tattoo collection.
He added tight black trousers, a pair of black boots and a silver chain necklace to complete his look.
The rapper, who recently bleached his hair back to platinum blond after months of being bubble-gum pink, had his long tresses styled partially in a bun, while letting the rest fall loose.
Jeannette McCurdy, Lily Collins, Keke Palmer and Joe Alwyn were also amongst some of the celebrities attending the star-studded event.
The Gala brings together notable figures across a range of industries and features a diverse array of up-and-coming talent.
Transformers star Megan opened up about the drawbacks of being considered a sex symbol in Hollywood and said she is yet to face ageism.
"As long as you are still a commercial commodity, they don’t come after you. So I haven’t experienced that side of Hollywood yet," she told TIME at the Gala.
Megan also said people "seem to not be able to value me for much more" than her looks.
She added: "I never had a problem being a sex symbol. I never thought that that was a negative thing," but added that it creates a "false narrative" when people overlook her intellect and humour.
