The pop stars might be two of the busiest parents in showbiz, what with their band commitments and various appearances on TV and radio, but they still managed to steal a few hours with Alaia-Mai this morning (16 October).
And we can't get over how cute they looked!
Doting on their adorable daughter (who is five-months-old this week) during a swimming lesson, Rochelle and Marvin looked picture perfect in a candid snap uploaded on Rochelle's Instagram page.
The Saturdays' songstress, 24, captioned the photo: "Family time." On Twitter, she added: "The best morning with my world." Aww!
Marvin, 28, also posted a link to the sweet picture and tweeted: "Swimming with my girls."
The couple have been squeezing in as much time with their tiny tot as they can, despite their packed work schedules.
Last month, Rochelle treated fans to a couple of glimpses of Alaia-Mai as she joined her in the studio and sat on her lap during a make-up session.
Beside the make-up picture, Rochelle wrote the caption: "Can I join in Mumma? Loves watching Mumma doing her make-up."
Alaia-Mai also supported her dad by making an appearance on the set of JLS' very last music video before they split up for good later this year.
Perhaps we'll see the little one cheering on Marvin on the set of The Voice in the coming months too, as he has now been confirmed as a co-host of the singing competition along with Emma Willis.
