Marvin Humes has revealed the first picture of daughter Alaia-Mai.

The JLS hunk and proud new dad - who welcomed his first child with The Saturdays singer Rochelle Humes on Monday (20.05.13) - was beaming with pride as he shared a snap of him holding his newborn on Instagram today (24.05.13).

Marvin, 28, is seen smiling from ear-to-ear while looking down at little Alaia in the photo, which is captioned: ''Daddy's Girl...❤''

The adorable picture also gives a glimpse into what appears to be the newborn's nursery, which features a dedication to each member of the family emblazoned on the wall.

The letters 'M', 'R' and 'A' - representing Marvin, Rochelle and Alaia respectfully - can be seen patterned diagonally in the background of the snap, with the letter 'M' in blue and the other two letters in pink.

In her first public comments since giving birth, Rochelle, 24, said she was ''blessed'' to welcome ''little angel'' and revealed that Alaia has already developed a bond with her father.

She wrote on Twitter yesterday (23.05.13): ''Thanks so much for all of your lovely messages. I feel so so blessed. Alaia-Mai is just a little angel. We're all very happy. Thanks again.

''Marvin is a great daddy. Absolutely in love with his princess. Definitely a daddy's girl situation already started. So beautiful x. (sic)''
