The Saturdays star has a jam-packed diary of meetings in the capital today (3 September) and who better to driver her to them than Marv.
While in the car, Rochelle took a selfie which showed the couple sitting side-by-side and looking pretty glam. Is Marvin even wearing a driving jacket?!
Commenting on the picture, the mum-of-one said: "Getting chauffeured around by this gent for a day of meetings in London @marvinhumes #fitdriver."
It's been a busy time for Rochelle lately. Throughout the summer, she and Marvin had presented ITV1's This Morning every Friday while Phillip Scofield and Holly Willoughby were on a break.
Meanwhile, Rochelle has also launched new pieces in her clothing collection with Very this week and has been hard at work with The Saturdays, who are going on tour this month.
The girls are been working up a sweat in rehearsals for their 'Greatest Hits Tour', which kicks off in Glasgow on Sunday (7 September), but it seems they have already perfected everything.
Earlier this week, Rochelle shared a photograph of her glittery microphone and told fans: "Just finished our last rehearsal before we go away!! #nearlytourtime." Exciting!
