The couple, who welcomed their baby girl Alaia-Mai into the world in May, were pictured hand-in-hand as they left Hakkasan restaurant in central London.
Wearing a bright red dress with black printed detailing, Rochelle was all smiles as she emerged into the street with her husband. She teamed her outfit with simple black courts and styled her hair in loose waves. And is that Rochelle's fave £9.50 lipstick we spy?
Marvin, meanwhile, looked super dapper in a duck egg T-shirt, jacket and blue jeans, topped off with a tan pair of boating shoes.
They were joined for dinner by Rochelle's Saturdays bandmates, Mollie King and Vanessa White, who were also pictured heading home at the same time.
No doubt pregnant Frankie Sandford was tucked up in bed after being told to cancel all Saturdays performances until after her baby is born.
Una Healy also wasn't pictured either, so perhaps she couldn't find a babysitter for daughter Aoife-Belle - or maybe she was looking after Alaia-Mai to give Marvin and Rochelle a night off!
Marvin certainly had reason to celebrate, as yesterday marked the five year anniversary of JLS. He tweeted: "#5YearsOfJLS what a journey..what great times we've had. Let's make sure the next 4 months are bigger & better than everything! Love u guys x"
