Billie Eilish fans have been left stunned after discovering she has famous parents -leading them to ask if she is a ‘nepo baby’.

The 23-year-old singer, who is widely considered one of the biggest pop stars in the world, isn’t just the only famous person in her family.

Billie found fame in the music industry at just fourteen years old and has gone on to win an impressive collection of Grammy, BRITs and Billboard awards.

However, diehard fans have only just realised both her parents are successful actors, having starred in some of the biggest movies and TV shows.

Billie’s mum Maggie Baird previously held a role in Friends, all the way back in 1999 before she was even born.

She appeared in season six, episode four which was titled ‘The One Where Joey Loses His Insurance’.

It saw Maggie play a casting director, in which Joey (Matt Le Blance) auditions for a part in front of her.

Joey needed the role in order to cover his medical expenses, after sustaining a painful hernia.

Unfortunately for the bachelor, he didn’t succeed in securing the part.

Maggie, 66, has also starred in 1989 thriller An Innocent Man, while other acting credits include The X Files, Six Feet Under and Bones.

Meanwhile, Billie’s father Patrick O’Connell is also a star in his own right, having been cast in the 2008 Iron Man movie.

He’s also appeared in The West Wing, Life Inside Out, Baskets and Hunter.

Fans flooded social media with comments, gobsmacked at the discovery, with one writing: ‘Both of her parents are actors.’ 

Another simply asked: ‘So Billie is a Nepo Baby?’

While one specifically addressed Maggie’s Friends appearance, writing: ‘I literally just watched this episode and now feeling annoyed that I didn’t notice this.’ 

A fourth said: ‘HOLY S**T I THOUGHT SHE LOOKED FAMILIAR!’ 

Billie’s older brother Finneas, 27, has also built a successful career for himself, working as a record producer. 

Billie isn’t afraid to push fashion boundaries and is known for her quirky style and different hair colours.

The singer, who has three albums to her name, is currently on a huge world tour which will be hitting the UK this month and includes a six-night run at London’s O2 Arena.

She has a sensational nine Grammy wins under her belt, as well as four BRIT Awards and two Oscars, all earned after less than a decade in the industry.

Recently, Billie and actor Nat Wolff, 30, finally confirmed to the public that they are romantically involved with one another after rampant speculation.

The pair were seen kissing on a balcony during an outing in Venice, Italy last month in images published by Deux Moi, after denying they were in a romance with one another.

The nine-time Grammy winner was seen snapping selfies with her new beau as she donned a striped green polo shirt with her black locks down.
