Los Angeles, California - Billie Eilish and Jesse Rutherford made their controversial romance red carpet official with a rather unusual set of coordinating outfits.

The new couple is snuggling up while stepping out in style.

The pair attended the 11th Annual LACMA Art + Film Gala together in on Saturday night.

The 20-year-old singer looked cozy with her 31-year-old beau, donning coordinating Gucci pajama sets and wrapping themselves in a large designer blanket.

Eilish wore a lace nightgown and robe adorned with the Gucci logo, while Rutherford wore a shirt and pants set with the same fashion-forward fabric.

The guest list at the star-studded gala also reportedly included Kim Kardashian, Kendall Jenner, Olivia Wilde, and many more.

The Bad Guy artist recently made her relationship with the Neighborhood frontman Instagram official. The post included photos of the pair's couple's costume for Halloween as a baby and an old man, pointing to criticism of their 11-year age gap. The costume choice sparked backlash when the photos first hit social media.

The two first sparked romance rumors last month after they were spotted having dinner together.

Despite the controversy surrounding their age, it seems that Eilish is getting to be cozy and happier than ever with her new man.
