We wouldn't normally think these famous ladies had similar tastes in fashion, but they've both snapped up this pink leopard print dress by Versus Versace.
We spotted Alesha rocking the designer frock at the star-studded Jog On To Cancer charity fundraiser in London last night (9 April).
The Britain's Got Talent star flashed her pins in the thigh-slit dress, with also featured cut-out details and safety pins near the neckline.
Alesha teamed her racy frock with sparkling gold heels and a pale pink clutch, leaving her long ombre locks flowing past her shoulders.
But unfortunately Katy pipped her to the post, as she wore the same dress back in December last year while attending Capital FM's Jingle Bell Ball.
Katy kept the rest of her look simple, teetering along in pointed black courts while wearing a gold bracelet and hoop earrings.
She also flaunted a glossy red mani and bright pink lips, sweeping her raven locks into a slick high ponytail. And check out that Angelina Jolie-esque leg pose!
