If you've seen the original 'Mulan' film, you'll be familiar with the song 'Reflection'.
Although the version in the film was sung by Broadway star Lea Salonga, Christina Aguilera recorded a pop version that she released as her first-ever single in 1998 when she was 17. It was a huge hit and led to a major record deal. A year later she released 'Genie in a Bottle' and the rest is history.
Now, with the live-action remake of 'Mulan' on the way, she's returning to her roots by recording a new updated version of the song.
She made the announcement at a gig in Las Vegas on Wednesday night, telling the crowd: "The live action Mulan is coming out by the way. You have to go see it.
"I recorded a new "Reflection" and new material for the movie. I've been working on that, but this is the original."
Given the fact that she sang the song at the Disney 2019 D3 Expo last year, her involvement isn't that surprising - but now it's official.
The 'Mulan' remake is out on March 27th in Ireland.
