Megan Fox and fiancé Machine Gun Kelly were spotted out and about in the Big Apple on Monday.

The 37-year-old actress — who recently announced she wrote a book of poems — turned heads as she rocked a fiery new look.

The bombshell sizzled in a bright red wig that was cut into a bob with face-framing bangs.

Fox paired it with a low-cut black satin mini dress that showed off her voluptuous chest and toned legs.

Meanwhile, her 33-year-old rapper/rocker love joined her in silvery gray relaxed fit Y2K-style pants and a tan ribbed tank top.

Kelly, whose birth name is Colson Baker, bared his fully tattooed arms in the sleeveless look.

He accessorized with silver-toned jewelry including a chain necklace and matching bracelets.

The father-of-one rounded out his trendy look with a pair of black and white Rick Owens sneakers.

Megan, who stars in the forthcoming Expend4bles movie, matched his footwear as she wore a pair of chunky black and white Oxford loafers.

And she drew attention to her chest as she donned a layered gold chain necklace with large, black stone pendant.

Additionally, she matched her nails to her tresses as she flaunted a long, pointy-tipped, blood red manicure.

The superstar’s visage was fully made up to accentuate her stunning features as she rocked winged eyeliner and long lashes.

Finally, the cosmetics look was completed with a matte pink hue coated on her plump pout.
