The Saturdays star was typically chic in her black and grey dress but gave the look a rock chick edge by throwing on a two-toned leather jacket.
For the second day in a row, we're also having serious handbag envy!
Rochelle and Marvin were recently announced as guest co-hosts for This Morning, so perhaps they were at the ITV studios for a pre-show meeting.
The couple announced on 6 August that they'll share the screen together on 23 August, adding: "The rumours are true for those of you who are asking! We're very excited!"
So are we!
Neither Rochelle nor Marvin are strangers to presenting. Rochelle appeared as a panelist on BBC Three's Sweat The Small Stuff right up until her maternity leave began earlier this year, while Marvin has a weekend radio slot at Capital FM
We're quite hoping that during their time on This Morning the new parents, who recently celebrated their first wedding anniversary, might share a new picture of their baby daughter Alaia-Mai, who was born on 20 May.
They've already given us two shots of the youngster - one of Marvin holding her when she's a few days old and another family shot - but we'd love another.
Marvin recently said he "idolised" his daughter, telling MailOnline: "We just never want to be away from her at the moment,' he added. 'It's hard to resist spoiling her, when we go shopping I just want to buy her everything , so we have to restrain ourselves."
But when asked if plans for a second child were already under way, he replied: "We've made no secret of the fact that we want to have a big family, but I don't think we're going to jump straight back into having another baby. Rochelle is just getting back to herself post-baby."
Rochelle returned from maternity leave in June, joining The Saturdays - and Prince Charles! - at the opening of a new Marie Curie Hospice in West Midlands, Solihull.
She's also just shot the group's brand new music video and has a main stage performance at next weekend's Virgin Media's V Festival ahead.
Marvin, meanwhile, is busy himself with JLS commitments, his Capital FM radio job and his DJ-ing.
