The Saturdays star Rochelle posted the photo to Instagram this morning, showing JLS' Marvin fast asleep, while holding onto Alaia-Mai's tiny feet.
Captioning the snap, Rochelle said: "Ahhh my beauts have gone back to sleep. This melts my heart." All together now, ahh!
Marvin and Rochelle, who welcomed Alala-Mai on 20 May, are clearly besotted, and Marvin recently told Reveal that fatherhood has changed him.
He told us in September: "I've definitely become more emotional. Nothing can ever prepare you for the love that you have for your child, ever. My little girl blows my mind every single day and I hate being away from her. I'm so so lucky."
Even at this year's Virgin Media's V Festival, Rochelle told us that she felt "sick" at having to leave Alaia-Mai at home for the first time. "That baby is just everything in my life," she added.
Even though Rochelle is busy being one fifth of The Saturdays, and Marvin is committed to JLS until the end of the year, along with his DJ slots at Capital FM and being the new co-host of The Voice UK, the first-time parents still make time for family outings.
Two weeks ago, Marvin and Rochelle treated Alaia-Mai to a day out at the farm. Marvin said at the time: "Weekend of nothing but family... My favourite times!! #blessed."
