Machine Gun Kelly and gorgeous fiancée, Jennifer's Body actress Megan Fox just nailed another coordinating couple look.

For their appearance at the 2022 Billboard Music Awards, the couple matched in their blingy, black-tie best -- a daring David Koma gown on the former Transformers actress featuring a thigh-high slit, built-in gloves and rhinestone flowers at the shoulders (on Fox) and a spike-accented suit with a cropped blazer, worn with a rhinestone and grommet covered dress shirt and studded boots (on Kelly). But it was their matching manicures that stole the show.

"I feel great! I don't have to do anything — I did all my work. He still has to perform," the actress said on the red carpet to a reporter.

For his big night at the Billboard Music Awards, MGK, né Colson Baker, teamed up with Marrow Fine Jewelry founder Jillian Sassone and his manicurist, Nails of LA founder Brittney Boyce, on a dazzling manicure boasting more than 10 carats of diamonds with a total value of $30,000.

"Creating MGK's diamond nails was a natural progression of where nail art and jewelry intersect," Sassone tells PEOPLE of concepting the look over several months.
