Heading into London, the pair took to the red carpet at the star-studded Glamour Awards looking just fabulous.
While Marvin cut an oh-so-dapper figure in a three piece suit, Rochelle proved she is a pro when it comes to getting all dressed up - giving Millie Mackintosh serious competition when it comes to all things boho.
Ditching her usual Hollywood glamour vibe for a more relaxed Bohemian look, Rochelle looked oh-so-gorgeous in her colour-block floor length dress. So, it's no wonder Marvin was beaming alongside her from ear-to-ear!
Her girly number featured a pleated body and scalloped top, making for a great red carpet look along with the Saturdays singer's braided locks.
Proving festival fashion can be wardrobe worthy outside of the fields, Rochelle swept her long tresses up into a tousled updo, plaiting the front section to frame her face. If only we knew how to master such a style!
On the beauty front, the 26-year-old kept things simple, opting for long fluttery lashes and a slick of gloss on her lips. To finish, Rochelle added an oh-so-cool gold arm bangle for a little extra sparkle.
Inside the showbiz bash, the couple joined the likes of pregnant Fearne Cotton, Ellie Goulding and her McBusted boyfriend Dougie Poynter and gorgeous girlband Little Mix.
Rochelle and Marvin's evening out saw the pair enjoy some quality time together, leaving their little girl Alaia-Mai to be looked after at home.
The proud parents recently celebrated Alaia's second birthday, throwing their daughter an in-credible Frozen-themed party to celebrate. It came complete with real-life Princesses Anna and Elsa, blue Olaf Jelly and matching cupcakes.
Rochelle and Marvin even kitted out Alaia in her very own Princess Elsa get-up, including personalised Frozen Converse. Now that is one cool two-year-old for you!
On her baby girl's special day, Rochelle told fans everyday is a joy being mum to her little princess. Aw!
Opening up to Reveal about Alaia-Mai recently, Rochelle told us her mini-me is starting to become a little character.
"[Alaia's] really got her own mind and is really opinionated," she told us. "She's becoming a little bossy, but it's quite funny."
Despite loving every minute of motherhood, Rochelle did admit she and Marvin won't be expanding their brood just yet.
She added: "Obviously I want more kids, but at the minute, I'm focused on the one I've got. The three of us are having so much fun."
