Jennifer Lopez wears black dress and diamonds for Taylor Swift and Travis Kelce’s wedding

Our fair lady.

Jennifer Lopez took to Instagram to show off her designer look for Taylor Swift and Travis Kelce’s star-studded MSG wedding Friday night.

The 56-year-old multihyphenate posted a few snaps of her Audrey Hepburn-esque dress, captioning the post with a simple champagne flute emoji.

Lopez wore a black velvet Bach Mai dress with a scooped neckline, dropped waist and full lurex skirt that hit just below the knees.

She paired it with black velvet platform heels and a suite of floral-inspired diamond jewelry, including a sparkling two-tiered necklace.

The “Office Romance” actress wore her hair in a textured chignon, per hairstylist Justine Marjan, and added a velvet headband.

She wasn’t the only one taking cues from Hepburn for Swift’s wedding weekend; the star’s BFF Selena Gomez wore a black Oscar de la Renta gown with a sleek bun and her own stack of diamonds to Thursday night’s more intimate rehearsal dinner.

Here’s latest on Taylor Swift and Travis Kelce’s wedding at MSG:

J.Lo has been friends with Swift for years, even making a surprise appearance onstage with the Grammy winner in 2013 during her “Red” tour for a performance of “Jenny from the Block.”

In a video posted on YouTube at the time of the performance, Swift introduced the star, calling the single her “hairbrush song” that she’d “blast” and “play over and over and over again” to sing “into the mirror.”

Lopez made time in her busy schedule for the nuptials, having performed at Prime Video’s Obsessed Fest one week ago in Los Angeles wearing a risqué catsuit covered in faux tattoos.

Other A-list guests at Swift and Kelce’s over-the-top, 1,000-person wedding included Ed Sheeran, Reese Witherspoon, Gigi Hadid, Brad Pitt and many more.
