Billie Eilish just confirmed that she will be singing the theme song of the new Bond movie! “No Time To Die” JAMES BOND. AND I AM SINGING THE THEME SONG. WHAAT" Eilish wrote in an Instagram post on Tuesday, January 14, as a caption to the poster which had the iconic James Bond's 007 written across it.

With the confirmation, Eilish became the youngest-ever person to record a Bond theme. Sam Smith was 23 when they recorded the 2015 theme for 'Spectre,' with his 'Writing's on the Wall.'

As the 18-year-old 'Bad Guy' singer was already rumored to sing the theme song of the next Bond movie, 'No Time To Die,' which will see Daniel Craig take on the British spy for the final time, the news sent her fans into a frenzy, as praises and heart emojis started pouring in the comments section of her post.

Earlier, she teased her fans at the possibility of doing so by posting photos of eight iconic Bond girls from the franchise’s 50-year history, which included Halle Berry playing Jinx Johnson from 2002’s 'Die Another Day,' Daniela Bianchi as Tatiana Romanova in 1963’s from 'Russia With Love' and Catherina Murino as Solange Dimitrios from 2006’s 'Casino Royale.'

At the time, she offered no explanation for the post, enjoying playing the guessing game with her fans. Oscar-winning composer Hans Zimmer confirmed on Monday that he will compose the score for the movie.

Her latest post, however, left no doubts in anyone's minds and also ended speculation over Beyonce being the favorite to sing what might go on to become an iconic number. Last week, Queen Bee's eagle-eyed fans noticed the singer may have dropped a rather large hint on Instagram while at the Golden Globes. In the last in a series of photos from the night, she was seen sipping 007's signature drink, a martini. "I think she's going to be in [the] James Bond project. Martini is his signature drink," wrote one and was soon followed by a barrage of similar tweets.
