It seems all three starlets have hit the high street and snapped up this collarless monochrome cover-up, £75 from Oasis.
Mollie - who has her own edit for Oasis called 'Loved by Mollie' - was ahead of the pack, sporting hers way back in April as she stopped by the Radio 1 studios in London.
The Saturdays singer went for a simple look, opting for black cigarette pants and a white top plus sophisticated pointed heels.
We then did a double take when we spotted TOWIE star Lauren rocking the same coat just a few days later (9 April) at the Jog On To Cancer fundraising event.
Lauren went for a slightly more colourful look, accessorising her white dress with red strappy heels from River Island and a fab lemon clutch by New Look.
And it seems the coat is pretty popular on the Essex scene, as we recently spotted Lucy wearing it too!
The pretty brunette - who has her own fitness business - was snapped heading to Billie Faiers' baby shower in Brentwood over the weekend (11 May).
Lucy flaunted her sunkissed pins in a cute yellow dress, completing her look with nude sandals plus a swoon-worthy Givenchy Antigona bag. Jealous!
So which one of these lovely ladies do you think wore the coat best? Let us know by voting below!
