All the Celebrity X Factor stars were out in full force for the show’s launch.
Zara showed off her cleavage in a blue ballgown with a raunchy neckline and revealing sheer side panels when she made a headline-grabbing appearance.
The daring dress featured a backless design and a cinched waistline that made the most of the reality star’s hourglass figure.
Her voluminous blonde curls sprung off her fantastic figure while she worked every angle on the red carpet among the stars.
Zara has formed band The Islanders with Love Island co-stars Samira, Eyal Booker and Wes Nelson ; the Love Island Supergroup will fall in the Groups category.
Band members Wes and Eyal, of 2018 Love Island fame, were stylishly in sync as they both dressed in black for the occasion.
Their former co-star and her fellow Islander bandmate Samira made an equally daring arrival as she put a lot of skin on display in a sheer dress and nude leotard.
The West End star turned heads while she tottered out onto the red carpet in sky-scraper heels to match her nude one-piece.
Silver and red gems adorned the transparent number which added a pop of colour to her stunning look.
Megan McKenna, of TOWIE fame, rivalled the Love Island girls’ stylish looks in her own plunging snazzy suit.
The High Heeled Shoes hitmaker complemented her patterned two-piece with a cherry coloured clutch bag for her red carpet essentials.
Megan highlighted her beauty with a dusting of make-up and she organised her golden crimped curls in a tidy fashion.
The reality star turned singer will compete as part of the Unders category for Celebrity X Factor which will kick off on Saturday.
She once famously beat Taylor Swift and Pink in the iTunes chart after dropping her single High Heeled Shoes in September two years ago.
Next on the red carpet was Victoria Ekanoye, from the Overs category, who stood out from the rest of the stars in a sunshine yellow ballgown.
Also in the Overs category, talk show host Ricki Lake opted for casual chic as she paired a dust grey jumper with a pleated white miniskirt, boots and a baker boy hat.
Quiz champion Jenny Ryan looked mesmerising when she twinkled among the stars in a glittering wrap dress.
Brendan Cole and Jeremy Edwards, who have formed a group for the show, showed off their playful side and their bond.
Kevin McHale dressed up his grey T-shirt with a casual blazer as he joined his Celebrity X Factor co-stars.
Simon Cowell has recruited Nicole Scherzinger and long-time warring partner Louis Walsh for his Celebrity X Factor panel.
Both Louis and Nicole’s working relationship with Simon goes way back to the early days of The X Factor.
Dermot O’Leary also will pick up the microphone to host the star-studded show.
Celebrity X Factor will air on Saturday October 12 at 8.35pm.
