Megan Fox rocks a blazer while Machine Gun Kelly wears a shiny jacket at his nail polish launch

They’ve been nearly inseparable since launching their romance last summer.

And Megan Fox and Machine Gun Kelly showed that their style was just as entwined on Saturday when they arrived together at the launch of MGK’s new UN/DN LAQR nail polish.

The 35-year-old actress and the 31-year-old rapper-turned-singer both looked fierce in complementary all-black ensembles for the launch party in West Hollywood.

Megan arrived in a striking black dress that she appeared to wear without a shirt.

She had a black metallic sheet on chains wrapping around her torso positioned between her cleavage, and she wore a thick black Cuban links style belt highlighting her hourglass figure. 

The Jennifer’s Body star blazer was decorated with a lustrous material and black beads and eyelets below her belt.

She completed her outfit with open-toe stilettos that strapped repeatedly around her ankles, and she carried a metallic silver handbag with her. 

Megan wore a splash of burgundy lipstick, and her raven tresses were styled in gentle waves cascading down her shoulders.

Machine Gun Kelly (real name: Colson Baker) matched her in a lustrous black vinyl suit with a double-breasted jacket featuring peaked lapels.

He also skipped a shirt and wore black patent leather shoes.

The rocker had some unusual accessories, including a silvery lip cuff with an ornate fang design that dangled over his chin.

He and Megan made their inseparability literal by both wearing long fake nails over their pinkies that were attached with a chain, meaning they could be more than a few feet apart during the event. 

They were celebrating the release of MGK’s new nail polish line UN/DN LAQR (pronounced: ‘Undone Lacquer’).

The brand initially features ten different colors, along with five top coats. 

In an interview with W Magazine published Thursday, the musician shared that he began experimenting with painting his nails when he was in high school, before he became interested in more intricate designs.
