Billie Eilish debuts dramatic new look and people are convinced she’s another celebrity

Billie Eilish has debuted a brand new look, but fans are convincing themselves it isn't her and is instead another huge celeb.

In an Instagram photo dump earlier this month, she posted pictures of herself with a strawberry blonde, shoulder-length bob and a side parting.

The Bad Guy songstress appeared to have ditched her signature long and dark hair for the new look which caught quite a bit of attention online.

The new aesthetic follows her dramatic 1950s period makeover in August, where she transformed into Esther Greenwood for her starring role in the film adaptation of Sylvia Plath's The Bell Jar.

In a mirror selfie, the 24-year-old pulled a silly face as she showed off the new hair-do, paired with a casual dark navy blue pullover, khaki pants, white DC Shoes socks and black Celine sneakers.

This is Eilish's first blonde colour since her Happier Than Ever era back n 2021, when she had ditched her signature acid green hair for a bleach blonde platinum look.

After debuting the drastic new style, she then featured in a John Hardy jewellery campaign along with her brother and fellow musician Finneas.

But fans quickly flooded social media comparing her new appearance to another huge star.

Billie's recent post also included snaps of her dog Shark and a picture of the sunset along with the simple caption: "Hi" marking a social media return after two months.

Many users thought she looked like British actress and Golden Globe winner Emily Blunt, sporting a similar hairstyle to the film star.

"That’s clearly Emily Blunt," one user posted, as another wrote: "billie eilish turning into emily blunt and i kinda like it."

Another comical post then quipped: "I'm just now learning that Billie Eilish and Emily Blunt have the same mom."

"Um who exactly is that because i am staring at it and it is definitely not billie eilish," penned another user.

In a previous interview with Elle, Billie explained how her platinum blonde hair prevented her from having privacy from the paps because it was 'so obviously' her.

“I couldn’t go anywhere with that hair because it was so obviously me. I wanted anonymity," she said at the time.

“I went to a park with a friend, and I was like, ‘No, I can’t take off my hood!’ I was terrified of the paparazzi and these stalkers I’ve had.

"I’ve had different coloured hair and vibes for everything I’ve ever done. I wanted this album to have its own thing."
