We can't wait to see the 'Love Me Like You Do' singer at this weekend's British Summertime at London's Hyde Park when she'll be performing before headliner, Taylor Swift.
And if her voice is anywhere near as fabulous as her new hair colour, it'll be a stormer!
Ellie took to Instagram on Monday (22 June) after switching up her hair from a warm, golden blonde colour – with oh-so-fashionable roots – to this all-over bleach job.
And we love it!
"Blonder-er for festival season," Ellie posted. "I bet my hair wishes I would just leave it the hell alone soz hair..." she added.
To be honest, it looks in pretty good condition to us, but yes, Ellie will definitely need to keep up with the conditioning masks if she wants to maintain soft and healthy-looking hair for the weeks to come. Especially with such a busy schedule including V Festival as well as all manner of festies across Europe, Canada and the US.
Makes us feel tired just thinking about it...
But we know Ellie loves Percy & Reed products so a good weekly dose of Totally TLC Hydrating Mask, £20, percyandreed.com should do the trick.
Ellie isn't the first to be adventurous with extreme hair colour in the last few weeks with Vicky Pattison going almost-black at the weekend and Amy Childs becoming a bottle blonde at the beginning of the month.
We're looking forward to Michelle Keegan going platinum blonde and Jennifer Aniston turning redhead in the coming weeks.
OK, maybe not – some of our favourite hair icons should definitely stick with their winning hair colours, don't you think?...
