The proud dad – who welcomed his first child with wife Rochelle Humes in May - confirmed alongside his band mates in April that JLS will call it quits at the end of 2013 following six successful years.
But before they bow out, they'll treat fans to a final album called Goodbye: The Greatest Hits and a 'Greatest Hits Tour'.
Yesterday, Marvin and band mates JB Gill, Oritse Williams and Aston Merrygold gathered to film their last-ever video as a four-piece.
And there were some very special guests on set: little Alaia-Mai and Rochelle!
Marvin tweeted: "Was lovely today that my Daughter got to see her Dad do his thing on our music video..we've shot 17 and she saw the last one! Special day."
Also on set was JB's long-time girlfriend Chloe Tangney, who tweeted: "@RochelleTheSats and I just surprised our boys on their last video shoot today!!"
It seems yesterday was a bittersweet day for all involved, with Marvin saying: "Last ever JLS video shoot finished..emotional! You guys will see it all very soon."
JB said ahead of the shoot: "Looking forward to the blessings today will bring...big day in JLS history!"
Oritse added: "Wow the very last ever JLS video shoot! I love my boys @AstonMerrygold @MarvinHumes @JBGill."
Announcing their split in April, the band said it had taken months to come to the decision and it hadn't been an easy one to make.
They shot to fame on X Factor in 2008 and despite not winning went on to achieve a string of chart hits including 'Beat Again', 'Everybody In Love' and 'She Makes Me Wanna'.
At the time they told fans: "It has been the most incredible journey over the last 6 years and we have achieved more things than we could have ever dreamed possible. Thanks to all of you guys, your support, your dedication and your love, you have changed our lives forever and we wouldn't be where we are today without you."
