But rather than going out on a date night together, the proud parents were actually spotted having fun in completely different parts of the country
Rochelle and her Saturdays band mate Vanessa White were snapped at a Brandy concert in London, while Marvin was working in Manchester, where he had a DJ set at Selfridges.
'What About Us' singer Rochelle joined Vanessa, Marvin's JLS band mate JB Gill and his girlfriend Chloe Tangney, and close friend Aaron Renfree for dinner before the group caught Brandy's performance at the Indigo2 at the O2 Arena in London on Tuesday night (24 September).
Dancer and choreographer Aaron tweeted a snap of himself, Rochelle and Vanessa looking rather impressed as they watched the American R&B star perform.
And it was a star-studded night as former X Factor contestant Jahmene Douglas was also in the audience. He tweeted at Rochelle: "Lovely meeting you :-) I hope all is blessed with the new famalam. Much love."
Rochelle later tweeted: "On way home from seeing @4everBrandy live OMG!!! That was no joke! She is unbelievable live!!"
Meanwhile, up in Manchester, her husband Marvin was impressing fans with a DJ set at Selfridges.
Audience members took to Twitter in droves to praise the singer's DJ skills. He later tweeted: "Just finished a sick set selfridges #SelfTrafford thanks peeps for the love."
And at the end of the night there were just two people on his mind.
"Planes, Trains, and Automobiles, what a day..covered about 800 miles today!!!! Love it..now home to my girls," he wrote.
