The former X Factor winner has embraced a lighter hair hue for a few years now, but she went over to the dark side last week in preparation for the fun and festivities that surround Grammy weekend...
Leona Instagrammed this snap (above) on Monday (9 February) to show off her beautiful red Michael Costello dress which she wore to the Creative Arts Agency's Pre-Grammy party at Sunset Tower in West Hollywood.
And while we love her glamorous, floor-length frock (and Leona's facial expression!), it was her new, dark hair colour that really caught our eye.
We're far more used to seeing the 'Bleeding Love' singer with a fairer hair colour so this deep, raven shade is a whole new look for Leona.
But it's one that definitely works!
"J'adore your hair," said one of her Instagram followers. Our sentiments exactly.
These days, Leona spends a lot of her time working in Los Angeles, California and she's previously been spotted at Nine Zero One Salon in Melrose Place, having her hair primped and preened.
So, we wonder if the guys at Nine Zero One are responsible for Leona's latest look?
They've been the creative geniuses behind some other pretty fabulous A-list hair makeovers including Vanessa Hudgens, Emma Roberts and Modern Family's Sarah Hyland, so it wouldn't surprise us...
C'mon guys, spill the beans!
