Billie Eilish and Boyfriend Jesse Rutherford Arrive Hand in Hand to the Oscars Afterparty

Billie Eilish and boyfriend Jesse Rutherford had a sweet date night at the Vanity Fair Oscars Party on March 12. The couple attended the annual afterparty for the first time, holding hands and sharing loving glances as they posed together on the red carpet in Beverly Hills. Eilish, 21, commanded attention in a black Rick Owens gown with a voluminous tulle skirt, while Rutherford, 31, wore a black suit and clown makeup. Inside the celebration, they linked up with Eilish's brother Finneas and his girlfriend, Claudia Sulewski, along with other stars like Regé-Jean Page, Sofia Carson, and Phoebe Tonkin.

Eilish, who won an Oscar for her and Finneas's song "No Time to Die" last year, has been linked to Rutherford since they were spotted kissing in October. She seemingly confirmed their relationship on Nov. 1 with an Instagram photo of their coordinating Halloween costumes, and they soon after made their red carpet debut in matching Gucci outfits at the LACMA Art+Film Gala.

Though their romance has sparked some debate due to their 10-year age gap, Eilish seems happier than ever with The Neighborhood vocalist. In a Vanity Fair interview last year, she said, "I managed to get my way to a point in my life where I not only was known by a person that I thought was the hottest f*cking f*cker alive, but [I] pulled his ass. Are we kidding me?" She added, "I pulled his ass, all me. I did that sh*t. I locked that motherf*cker down."

Eilish and Rutherford were among plenty of other celebrity couples who partied it up at the post-Oscars soirée. Cardi B and Offset shared a sweet kiss on the red carpet, Oscar nominee Austin Butler brought girlfriend Kaia Gerber as his date, newly engaged duo Rebel Wilson and Ramona Agruma put their love on display, and Adam Levine and Behati Prinsloo made their first joint appearance since welcoming their third child.
