Fans Are Talking About Billie Eilish’s Brother Dating Someone Who Looks Like Her
Finneas O’Connell and Claudia Sulewski are once again in the spotlight as social media users discuss the resemblance between Sulewski and Finneas’ sister, Billie Eilish. The couple has been together since 2018, but fans have reignited debates about how similar Sulewski looks to the pop star.
The conversation online has ranged from playful jokes to sharp criticism about their facial features and overall look. Finneas is known for his close relationship with Billie, serving as the main producer and co-writer for her hit albums.
Because he and his sister are often seen together, some people find it strange that his girlfriend is said to look like her. One social media user wrote that dating someone who could pass for your sibling’s twin is bound to stir controversy, while another claimed that Sulewski resembles Billie’s family more than she does Finneas himself.
Despite the backlash, many fans have defended the couple. Supporters argue that having a certain “type,” like brunettes with large eyes, is not unusual and does not mean anything deeper. One fan said the internet is simply doing the most over nothing, pointing out that the couple has been together for over seven years and is reportedly engaged.
People mad at Finneas for dating someone who looks like Billie? That's some next-level parasocial creepiness. They're happy, leave them alone.

Claudia Sulewski has also built her own career outside of her relationship. She first became known as a beauty YouTuber under the name BeyondBeautyStar and later expanded into acting and business. In 2023, she launched a luxury body care brand called Cyklar, which has been a big success. She has also acted in projects like I Love My Dad.
Finneas has been busy with his music career as well. This year, he and Billie made history at the 68th Grammy Awards, winning Song of the Year for “Wildflower” and becoming the first trio to win that category three times.
He also defended his sister after her anti-ICE acceptance speech drew criticism, taking to Threads to voice his thoughts about the backlash. In addition, he recently finished touring for his solo album, For Cryin’ Out Loud!, which shows a more traditional studio sound compared to his earlier bedroom producer style.
Sulewski has stayed involved in Finneas’ work, even appearing in the music video for his latest album’s title track. While managing her own projects, she remains a part of his creative world. Finneas has been producing for some of the biggest names in music, focusing on his work rather than online commentary.
In addition to music, Sulewski continues to grow her business and public presence. She is working on new acting projects while promoting her skincare line, and Finneas is set to release new music and continue producing for other artists. Their busy schedules show that they are both committed to their careers as well as their relationship.
