Selena Gomez twins with Benny Blanco’s mom and sister-in-law at Lil Dicky’s wedding

She’s already dressing like the fam.

Over the weekend, Selena Gomez accidentally twinned with fiancé Benny Blanco’s mom and sister-in-law in fiery red dresses.

Blanco’s older brother, Jeremy Levin, shared a photo of the trio at rapper Lil Dicky’s wedding on his Instagram Story, before his wife, Evi Levin, posted a similar shot, revealing that the matching moment was “Not planned 😅.”

Gomez, 33, brought the heat in a scarlet red Cult Gaia midi dress ($498) with a high neckline and open back.

The Rare Beauty founder accessorized with matching cherry-colored Charles & Keith bow-adorned heels ($89), a black leather Valentino top-handle bag ($4,100) and gold diamond Gabriel & Co. drop earrings ($4,150).

In another snap, Gomez bundled up in a black furry coat as she smooched her soon-to-be husband’s cheek.

Blanco’s mom, Sandra Levin, meanwhile, wore a gown with a mermaid-style ruffled skirt, while his sister-in-law opted for a one-sleeve number.

Gomez posted pictures from the evening on her Instagram, captioning the slideshow, “About last nights wedding 💒”

The “Lose You To Love Me” singer included pics of the groom, whose real name is David Andrew Burd, and his now-wife Kristin Batalucco.

Gomez also took the chance to promote her new Rare Beauty perfume ($75), sharing a photo and video applying the product on her neck.

Blanco and Lil Dicky have been close pals for years and have collaborated on songs together, including “Earth” and “Freaky Friday.” Blanco also frequently appeared on the rapper’s HBO show, “Dave.”

They’ve also shared highlights of their friendship on social media. “Happy birthday to the best friend @itsbennyblanco,” the rapper wrote in an Instagram post, honoring Blanco’s big day in March.

Gomez and Blanco’s next wedding might be their own.
