The `She Bangs` singer`s two-year-old twin sons Matteo and Valentino have made him a lot less selfish because he always thinks of them before himself.

When asked what he has learnt from his children, Ricky said: "Heavy lessons about simplicity and unconditional love. I don`t want to sound cliche, another father talking about unconditional love, but man, that`s the way it is. You hear it all the time, but when you feel this other branch of love getting stronger and stronger every day, it`s just amazing."

The 39-year-old pop star says hearing his sons - who were born via a surrogate mother in August 2008 - tell him they love him is the best thing that has happened in his life.

He told Parade magazine: "Every day they teach me different things. The love is there. When you have a two-year-old saying every other hour, `Papi, te amo. Papi, I love you,` it can`t get better."

It seems Matteo and Valentino are following in their father`s musical footsteps as they both love instruments.

He said: "The other day I took them to a toy store and they went straight to this tiny piano. And I`m like, `Look at the robot!` But no, it was the piano - both of them. So it`s very beautiful.
