Billie Eilish with BF: Together in sleepwear

Billie Eilish and Jesse Rutherford marked their new status as a couple by draping themselves in Gucci sleepwear in the LACMA Art + Film Gala 2022 at the Los Angeles County Museum of Art on 5 November.

The multi-award-winning singer-songwriter Eilish wore a silk floor-length nightgown with matching sleeping mask on her head, while The Neighbourhood lead singer Rutherford was in pajamas, fuzzy slippers and feigning sleepiness with yawns.

Topping their coordinated look, the young lovers draped a Gucci blanket over themselves while ambling down the purple carpet.

Their appearance in a public event happened only days after Eilish on Instagram posted photos of her and Rutherford, apparently making fun of their age gap.

Eilish, 20, and Rutherford, 31, were first seen dining at the Los Angeles vegan restaurant Crossroads Kitchen on 13 October.

They were likewise spotted holding hands while leaving Halloween Horror Nights at Universal Studios in LA.

On 19 October, they were caught kissing outside an Indian restaurant in Studio City, California.

Eilish and rapper Brandon Quention Adams had been dating for almost a year before breaking up in 2019. She was most recently linked to Matthew Tyler Vorce.

Rutherford previously dated model Devon Lee Carlson for six years. They split up in 2021.
