Just how cute is she?
The tot - who is the spitting image of her popstar parents - was born on 20 May, and posed with her parents for a family portrait, which Marvin tweeted.
"We know you guys have been wanting to see a picture of our little Princess. Mummy and Daddy are very over protective but here's a precious picture, she's a little camera shy x," he wrote.
JLS singer Marvin teased us with a snap of his daughter after her birth, which didn't reveal her face.
He recently told Entertainmentwise how he is loving being a daddy.
“It's just the most beautiful feeling. You can’t put into words how incredible it is and how it just fills you with such a lovely feeling. We’re both very, very lucky," he said.
What a beautiful family!
