Megan Fox is wasting no time showing off her maternity style.

After announcing her pregnancy earlier this week, the actor flaunted her baby bump in a daring ensemble, taking a cue from Rihanna and her lingerie-forward maternity looks. On Friday, Fox could be seen posing in a sheer black lace gown from Seks, courtesy of snaps shared to her makeup artist Jenna Kristina’s Instagram.

Fox, who is expecting her fourth child—her first with boyfriend Machine Gun Kelly—leaned into a gothic aesthetic for the night. Her ensemble included a plunging neckline, bell sleeves, and cutouts on either side of her waist. Underneath the barely-there dress, she wore a matching black bra and lacy thong, leaving her baby bump exposed.

The Jennifer’s Body actor accessorized with a black lace veil, which partially covered her waist-length black hair, styled in loose waves. She complemented her natural pregnancy glow with black winged eyeliner, as well as a swipe of peach lip gloss.
