The Saturdays singer stepped out on the red carpet with husband Marvin Humes this week at the National Television Awards and looked stunning in a floor length purple gown by Dolce & Gabanna and gorgeous soft curls in her hair.
However, underneath her glamorous dress Rochelle was hiding a pair of body shaping pants to help her appear as trim as possible.
She admitted: "I've got Spanx on and I think I will wear Spanx for the rest of my life!"
Although hubby Marvin was quick to dismiss Rochelle's claim as a joke and insisted that she was just being modest about her enviable figure, Rochelle quickly replied: "No, I am. You haven't seen them yet!"
Well, we never would have guessed!
Rochelle, 24, gave birth to her daughter Alaia-Mai last year and has been working hard in the gym with a personal trainer to shift the baby weight.
And it is clear to see that all of those sessions have paid off - Spanx or no Spanx!
She and JLS singer Marvin enjoyed their first date night in weeks at the NTA ceremony in London on Wednesday (22 January). So it's no wonder they intended to make the most of it.
"It's really nice to have a date night, it's our first for a while so I think we will have a few cocktails," Rochelle said. "My mum is on watch [with the baby] tonight. It's so funny because I tell my mum what to do with Alaia and she says 'Rochelle, you forget I raised you!' It's like I'm telling her how to do her own job."
Despite the loved-up couple and their little girl just returning from a holiday in the Maldives, Marvin has plans to whisk Rochelle away again next month, as part of a special Valentines Day treat.
"We're going to be in Dubai for Valentine's Day, he said. "I'm taking my wife on a nice trip."
