The 22-year-old actress, who plays Bethany Platt in the long-running ITV soap, took to Instagram to share her favourite memories from the past year with her 237,000 followers yesterday.
Lucy reminisced about dramatic Coronation Street moments, nights out and family events in the montage, which featured adorable snaps giving her fans a rare insight into her life off-screen.
One clip, however, drew more attention than the rest, and saw the blonde bombshell partying the night away in a seriously plunging gown which was slashed to below her bust.
Lucy opted to go braless in the sensational floor-length frock as she danced for the camera, clutching a drink in one hand and pumping her first in the air enthusiastically.
The star almost flashed a lot more than intended with her energetic dance moves as her assets threatened to spill out of the low-cut neckline.
She also added several sizzling holiday snaps to her 2017 review, including throwbacks of her dressed in a racy yellow swimsuit.
She put on a seriously saucy display in the plunging one-piece earlier this year when she uploaded a series of red hot pictures from her holiday in the Caribbean to Instagram.
Lucy sent temperatures soaring as she flaunted major cleavage in the jaw-dropping snaps, showcasing her shapely pins and enviably slender waist as she posed on a swing against the breathtaking backdrop of the turquoise ocean.
She also stood up to tease fans with a glimpse of the rear view, turning around to show off her pert posterior in the patterned number.
