Billie Eilish fans think that her brother’s girlfriend looks just like the singer.
The ‘Bad Guy’ artist, 20, works closely with her older sibling, Finneas O’Connell, 25, on creating her music.
While Eilish pursues singing, her brother has worked behind the scenes, having written a staggering 144 songs in total, including Eilish’s ‘Ocean Eyes’ and ‘Happier Than Ever’.
And in the past, his younger sister has stressed that her best music has always involved Finneas.

At the moment, the brother and sister are both in relationships, with Eilish’s recently making headlines.
The young singer is currently dating Jesse Rutherford, 31, and fans have remarked on the 11-year age gap.
However, O’Connell’s girlfriend has now been brought to attention.
Finneas is in a relationship with 26-year-old YouTube star Claudia Sulewski.
They’ve been dating since 2018 and according to J-14, the pair actually met through a dating app.
O’Connell has previously revealed that his girlfriend has played a big part when it comes to the music he produces.
He told Us Weekly: “Claudia has been a huge influence on my music in terms of just like how important she is to my life.”
“I think I’ve always tended to write about my true real-life experiences and she’s definitely at the core of all of that. So there’s a lot of songs about Claudia.”
While many fans have gushed over the happy young couple, others have begun to scrutinise their relationship, with some commenting on the similarities between Eilish and Sulewski.
Alongside a skull emoji, the page wrote: “People think Billie Eilish’s brother is dating a girl that looks just like her.”
The post has garnered over 66,000 likes, while hundreds have taken to the comments and agreed that the two look ‘similar’.
One wrote: “They look similar ENOUGH for it to be kinda ick.”
“I thought I was the only one who noticed… OK then, it’s really strange!” added another.
While a third said: “If I didn’t know Billie and you told me they were twins I’d believe you 100%.”
“Her side profile is literally Billie,” someone else remarked.
While a fifth commented: “Nah, he’s dating Billie’s clone.”
However, others have taken to the comments and insisted that they don’t look that similar.
“Noooo,” one penned. “They don’t look the same at all.”
Another asked: “WHERE’S the resemblance?”
A third remarked: “Reaching.”
“They look different,” a fourth insisted.
