Megan Fox Wears a Plunging Corset While MGK Paints Her Nails Blue

Megan Fox and Machine Gun Kelly promoted their new nail-polish collection for Kelly's brand Un/Dn Laqr on Instagram on Thursday night. While riding in the back seat of a car, Kelly, 32, touched up his fiancée's manicure in the Past Life shade, described as a bright lapis lazuli blue.

Fox, 36, was sporting her signature style, including a zipper-front denim corset with contrast stitching styled with a pair of matching cargo pants, plus a black fuzzy bucket hat — the latter accessory being an addition to her collection of red and purple iterations. The "Good Mourning" actor's sultry take on this classic '90s combination was completed with a dark cat eye and softly lined roseberry lip, with a subtle dusting of peach blush. Meanwhile, Kelly drew attention with his own sky-blue smiley-face-printed coordinates, and his nails boasted a black-and-white checkered pattern.

Of course, this isn't the first time the duo expertly pulled off an in-sync fashion moment. They wore varying interpretations of the all-denim uniform at "Jimmy Kimmel Live" last week, and they attended the GQ Men of the Year party in Hollywood on Nov. 17, each showing off black skin-revealing designs. For that occasion, Fox was in a netted and satin-paneled Christian Siriano dress and Kelly was in a cutout turtleneck and jacquard leopard trousers.

Meanwhile, Fox's most significant textured hat to date is still the oversize pink feathered topper she wore as a silent nod to Pamela Anderson at the Audacy Beach Festival in Fort Lauderdale, FL, on Dec. 4.
