`The Best Thing About Me Is You` singer - who is openly gay - already has twin sons Matteo and Valentino, two, by a surrogate mother, but admits he would love to expand his family further.
He said: "Fatherhood is incredible! Every day is something different. Matteo and Valentino, they`re constantly ganging up on me but I can take it! They`re amazing - I want more. This is only the beginning of our family."
When asked how many children he was considering having, he added: "I don`t know. Maybe one, two more, but yeah, definitely. I need daddy`s girl."
Though the 39-year-old singer loves fatherhood, he admits the arrival of Matteo and Valentino completely changed his life because of their sleeping patterns.
He told Miami radio station Y100: "Life changes! You have to sleep because you are not going to sleep ever again!
"Babies wake up every two hours. At 7 o`clock you are awake. For me, I was a night owl in the past, but now, I`m up, I`m working, I`m already dealing with the kids."
