The Saturdays singer wed the former JLS star four years ago today (27.07.16), and in a gushing Instagram post, she spoke at her joy of being his wife.

Posting pictures from their wedding photobooth, Rochelle wrote: "Happy 4th wedding anniversary to the only man for me. My absolute world. Love you forever."

And Marvin - who has a three-year-old daughter Alaia-Mai with Rochelle - also took to social media to pay tribute to his gorgeous wife.

He wrote: "Happy 4th Wedding Anniversary to the love of my life @RochelleHumes everyday just gets better.. I love you (sic)."

Marvin, 31, recently revealed how he still can't believe that he got to marry 27-year-old Rochelle.

He said: "I fancy Rochelle massively and constantly find myself looking at her thinking, 'Wow, that's my wife.'"

Marvin also said how the couple don't want to wait too much longer before giving Alaia a brother or a sister.

He shared: "I'm always broody! I love having that little baby in your arms. Rochelle is more broody now than ever because two of her best girl friends are pregnant.

"It's all up to the big man upstairs. I think we'll have number two within the next year to 18 months, before Alaia is four."
