This huge A-lister looks unrecognisable in a childhood photo before she grew up to be one of the biggest stars in the world after finding fame at 14-years-old 

In the unearthed picture the celebrity is seen as a toddler before she found fame and won an impressive collection of Grammy, BRITs, and Billboard awards – but can you guess who she is?

That’s right, it’s Billie Eilish!

The 23-year-old has shared the throwback photo of herself to Instagram a number of  times to celebrate her birthday over the years.

Billie, who has three albums to her name, is currently on a huge world tour which will be hitting the UK next 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.

In recent days, 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 earlier this 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.

The Wildflower singer beamed as she spent time with the actor, who has appeared in  2014’s The Fault in Our Stars and 2015’s Paper Towns. He also has a musical background as a composer and musician.

That’s right it’s Billie Eilish. The 23-year-old shared the throwback photo of herself to Instagram to celebrate her birthdays over the years

‘The couple were locked in a passionate kiss on a balcony, a scene straight out of a romance novel,’ a report from the outlet Deux Moi read. 

‘Adding to the dreamy atmosphere, they were seen sipping champagne and soaking up the Italian sun, clearly enjoying a romantic European getaway.’

In images snapped in Italy, both appeared to be in a great mood as their bond appeared to be going in a more public direction. 

Daily Mail has reached out to reps for both parties for further comment. 

The public display comes nearly one year after Billie released the music video for her single Chihiro, which featured Natt as her love interest. 

Billie, who directed the music video, described the relationship between their characters in the video as an ‘inescapable connection’.

The track was the second single from her album Hit Me Hard and Soft, coming on the heels of her first release from the record, Lunch.

It comes after Billie, 23, and Nat Wolff, 30, confirmed their romance with a display of PDA in Venice, Italy earlier this month. The two were pictured last year on the set of a music video they collaborated on

Billie said in a news release that she had ‘envisioned a dream-like narrative’ for the music video.

In the music video, the pair make their way out of the building and into a grassy field, where they playfully wrestle and eventually embrace one another.

The idea behind the interaction between the characters, according to Billie, was the ‘external expression of an internal push and pull, as our deepest feelings of fear, love, or desire inevitably catch up to us, no matter how hard we try to run away.’

On Spotify, the song has been played more than 853million times over the past year.
