The mum-of-one showed off her smoking hot bod at the glitzy event held in London's super-swanky Grosvenor Hotel and slipped into this show-stopper of a black gown that gave us a cheeky glimpse of her cleavage!
Expertly managing to avoid baring her assets as she struck a dozen stunning poses for the adoring paparazzi, Rochelle looked like a Hollywood superstar ready to take the red carpet by storm.
The TV presenter who has been a super-busy bee with filming this year's talent show series held on to a suited and booted, very dapper hubby Marvin Humes, before joining the rest of the celeb guests including Katie Piper and Fleur East.
During the evening, Roch took to Instagram to post a selfie with One Direction's Niall Horan which she accompanied with the cutest caption, like, ever! Giving a pout-y Niall a little smooch, Rochelle simply wrote, "Son/Brother <3."
Even though she looked nothing but stylish, Rochelle recently admitted that she has got it wrong in the past, and spilled the beans on her S Club Juniors days!
Speaking in an exclusive clip as part of Very's collaboration with 4Music and The Box Plus Network, Rochelle revealed, ""My look has evolved like everyone else's," she says. "But I started in S Club Juniors when I was twelve and I guess it's not a normal situation for everyone to know what outfit you're wearing when you're 12!"
She continued, "Everyone looks back at choices they've made in the past and thought, "Goodness me, what was I thinking?!"
Hard to imagine now, right?
