Billie Eilish’s Brother Faces Backlash After Fans Say His Girlfriend Looks Just Like Her
The relationship between Finneas O’Connell and Claudia Sulewski has recently become the focus of a resurfaced online debate. While the couple has been together since 2018, social media users have reignited a controversy regarding the physical resemblance between Sulewski and Finneas’ sister, global pop icon Billie Eilish.
This comparison has unleashed a wave of commentary, ranging from lighthearted jests to sharp criticism regarding the similarities in their facial structures and general aesthetic. Finneas has maintained a famously close personal and professional bond with his sister, serving as the primary producer and co-writer for her record-breaking discography.
Because the siblings are so often seen together, some onlookers find the perceived likeness between his partner and his sister to be unsettling. Critics on various platforms have not held back, with one user suggesting that dating someone who could pass for your sibling’s twin is a recipe for scandal, while another pointedly noted that Sulewski looks more like Billie’s family than Finneas himself.
Despite the noise, a significant portion of the fanbase has rushed to the couple’s defense, dismissing the uproar as a recycled narrative from years past. Supporters argue that having a specific “type”—such as brunettes with large eyes—does not equate to a deeper psychological issue.
One defender noted that the internet is simply doing the most over nothing, emphasizing that the couple has been steady for over seven years and is reportedly engaged, suggesting that the supposed resemblance is a non-issue for those actually involved in the relationship.
People mad at Finneas for dating someone who looks like Billie? That's some next-level parasocial creepiness. They're happy, leave them alone.

Beyond the shadow of this controversy, Claudia Sulewski has established herself as a powerhouse in the digital and entrepreneurial space. Originally gaining fame as a beauty YouTuber under the moniker BeyondBeautyStar, she has successfully transitioned into acting and business.
In 2023, she launched Cyklar, a luxury body care line that has seen massive commercial success. She has also showcased her range as an actress with roles in projects like I Love My Dad.
As of this year, Finneas is reaching new milestones in his own right, having recently made history at the 68th Grammy Awards. He and Billie Eilish took home the trophy for Song of the Year for their hit “Wildflower,” making them the first three-time winners in that category’s history.
Finneas was also recently seen defending his sister after her anti-ICE acceptance speech sparked political backlash, famously taking to Threads to criticize powerful old white men who were outraged by her statement.
In addition to his collaborative wins, Finneas finished touring in support of his sophomore solo album, For Cryin’ Out Loud!, which features a more traditional studio sound compared to his “bedroom producer” origins.
Interestingly, Sulewski remains a central part of his creative world, even starring in the music video for the album’s title track. With a schedule of production work for some of the biggest names in music, Finneas appears focused on his craft rather than the opinions of social media critics.
