Megan Fox Wears Ultra-Revealing Cutout Gown, Kisses Machine Gun Kelly on the 2021 BBMAs Red Carpet

The couple arrived at the 2021 Billboard Music Awards in two truly head-turning looks. Fox, 35, channeled her sultry, sexy side in a risqué black Mugler gown with a crisscross cutout bodice that left very little to the imagination. The abs-and-cleavage-baring top was paired with a sheer, ruched midi skirt (which originally debuted at the brand’s Spring/Summer 2021 show modeled by Dominique Jackson) and ankle-strap Jimmy Choo pumps.

The super-sexy, ultra-revealing look will go down in red carpet cutout history — even giving Kim Kardashian’s ‘boob belt’ dress (also by Mugler) a run for its money.

As for Kelly, 31, he rocked a deconstructed tuxedo with an unbuttoned, untucked white shirt, paired with metallic nail polish, necklaces and in an interesting twist — a black tongue — which he flashed to the photographers on the carpet.

Kelly (born Colson Baker) is up for three nominations tonight, including Top Rock Album for Tickets to My Downfall, Top Rock Song with “my ex’s best friend” featuring Blackbear and Top Rock Artist — which he won.

Last weekend, the couple had another glamorous night out as they celebrated Fox’s 35th birthday festivities with dinner in Santa Monica.

Fox sizzled in a red hot blazer with flared pants, matching bra and platform heels, while Kelly complimented her in a navy blue and red turtleneck, gray slacks and black boots with red shoelaces.

The duo’s sexy red carpet date night comes as they hit the one-year anniversary since being first spotted out together in May 2020. “Megan is very happy,” a source recently told PEOPLE. “They got serious quickly and have a great relationship.”
