The Saturdays singer wowed in a floor length embellished nude gown with a dramatic train at the Grosnevor Hotel in central London on Monday evening (7 October).
Very Jennifer Lopez, don't you think?!
We're also loving the mother-of-one's beautiful side braid and berry coloured pout. Just stunning.
Rochelle walked the red carpet at the event with Saturdays band mates Mollie King, Una Healy and Vanessa White, leaving JLS star husband Marvin to go solo for the cameras.
Marvin tweeted ahead of arriving: "On my way to @PrideOfBritain awards..it's always a very inspirational evening..looking forward to it."
The couple, who are parents to four-month-old daughter Alaia-Mai, reunited inside the venue and were later seen holding hands as they arrived back at their London hotel afterwards.
The Pride of Britain Awards recognise the unsung heroes among us and is always a glittering affair attended by politicians and a string of famous faces.
Rochelle tweeted afterwards: "Well that was a lovely evening! Met some true heroes! A pleasure to be in that kind of company! #prideofbritain."
It was a busy day for Rochelle, who was up early to perform 'Disco Love' with The Saturdays on Daybreak before undertaking a long day of promotion ahead of the release of album Living For The Weekend on 14 October.
Marvin, meanwhile, has just started filming his new role as co-host of The Voice UK, and been promoting JLS' last-ever single 'Billion Lights'.
