Megan Fox is not exactly a fad follower, preferring to forge her own path in life, but she did make an exception for the greatest fad of all time (in my completely impartial and totally professional opinion), the Barbie pink fad. But there is a deeper reason for her embrace of bright colors.

While attending the premiere of her fiancé's autobiographical documentary, "Machine Gun Kelly's Life in Pink," in New York City, the actress wore white blonde and pink balayage, a bit Kardashian-Jenner-esque, but jet black The new hairstyle is a bit Kardashian-Jenner-esque, but looks great on Fox, who is used to seeing jet-black hair, and is right on theme.

To complement her pink hair, Foxx wore a strappy, vintage-style pink mini-dress with pink strappy sandals. Machine Gun Kelly himself coordinated with his fiancée in a bright pink and blue cropped sweater. He also rocked a new bright pink hair color. It's truly a winning look.

The documentary, which airs on Hulu, follows Kelly's life and some of the most difficult events he has experienced, including being held at gunpoint while his daughter was in the car, being kicked out of his father's house, and being misunderstood in show business. The trailer can be viewed here.

Foxx and Kelly showed off their pink hair in matching outfits again a few days later after their show at Madison Square Garden. We like the overall vibe.
