February 3, 2026 — The Grammy Awards 2026 may be over, but Billie Eilish remains one of the most talked-about stars from the night. While her powerful speech criticizing ICE policies earned praise, it was her sparkling diamond ring that grabbed instant attention. As Billie walked the red carpet, fans quickly began speculating whether the singer was secretly engaged to her boyfriend, Nat Wolff.

The rumours grew stronger when Billie Eilish and Nat Wolff were seen sitting closely during the ceremony. The couple shared smiles, laughter, and a celebratory kiss after Billie won Song of the Year. Although neither Billie nor Nat has confirmed an engagement, their public affection fueled curiosity about Nat Wolff and their relationship.

Nat Wolff is an American actor and musician who was raised in a creative household. He is the son of actress and filmmaker Polly Draper and renowned jazz pianist Michael Wolff. Nat first became famous as a child star on Nickelodeon’s hit show The Naked Brothers Band, which was created by his mother. He starred alongside his younger brother, Alex Wolff, and quickly became a familiar face on television.

As Nat grew older, he successfully moved into film acting. He appeared in popular movies such as The Fault in Our Stars, Paper Towns, and Mainstream. Alongside his acting career, Nat continued pursuing music. He and his brother formed the band Nat & Alex Wolff, releasing multiple albums and performing internationally. Their music career reportedly brought Nat closer to Billie Eilish after he opened for her on the Hit Me Hard and Soft tour.

Billie Eilish and Nat Wolff reportedly first met at the Academy Museum Gala in Los Angeles in late 2023. The two gradually formed a close bond and connected over shared experiences. Both have openly spoken about living with Tourette syndrome and growing up in the spotlight at a young age. Their connection became more noticeable when Nat appeared as Billie’s love interest in her 2024 music video CHIHIRO, sparking early dating rumours.

Speculation intensified in June 2025 when photos of the couple kissing on a balcony in Venice, Italy, surfaced online. Since then, Billie and Nat have been spotted together multiple times in New York City. They were seen attending theatre shows and spending time in the East Village. Their appearance together at the 2026 Grammys marked their most public outing so far as a couple.

Before dating Nat Wolff, Billie Eilish had several high-profile relationships. She previously dated actor Matthew Tyler Vorce and rapper Brandon “Q” Adams, relationships that were featured in her documentary The World’s a Little Blurry. Her relationship with Jesse Rutherford from 2022 to 2023 also gained attention due to their age difference. Billie has also been open about her sexuality and shared that her song Lunch helped her embrace her attraction to women.

For now, Billie Eilish and Nat Wolff have stayed silent about the engagement rumours. However, their chemistry at the Grammys 2026 has convinced many fans that their relationship is serious and growing stronger.
