Marvin made the confession today (17 February), adding that he believes his 21-month-old daughter developed a taste for The Saturdays while Rochelle was pregnant.
Speaking to the Daily Star, Marvin admitted: "She's obsessed with her mum's songs. I give up, she's a big Saturdays fan from being in the womb."
While Rochelle found fame in tween pop band S Club Juniors, Marvin didn't get his break into the music industry until 2008, when JLS appeared on The X Factor.
After six years together, the band split in April 2013 and Marvin has been busy ever since working with his new electronic dance trio LuvBug. Thankfully, Alaia IS a fan of their new single, 'Revive'.
"She bops along in her carseat, going 'Mummy, it's daddy's song!'."
Wow, it sounds like someone is set to following in her pop star parents' footsteps!
Meanwhile, last week Marvin, Rochelle and Alaia took some time out and headed to Dubai for a relaxing holiday.
While there, Rochelle was pictured enjoying a cuddle and a kiss with Alaia by the pool.
She might like daddy's new song, but we think this tot is a mummy's girl at heart!
