The 39-year-old singer - whose two-year-old sons Valentino and Matteo were born via a surrogate mother in 2008 - explained there is always a party going on in his home now the twins have arrived, so he's getting used to not having much sleep.

He explained: "They're a little hurricane in my house. At 7 o'clock in the morning, there's a party going on! My mother told me, 'Ricky you're never going to sleep ever again in your life, now because they're babies and when their teenagers because they don't come back home!'

"So, it's getting used to the idea of not being able to sleep."

The 'She Bangs' hitmaker also revealed he has had to turn his tour bus into a playroom for the twins, so they are able to accompany him on the road.

Ricky added to US TV show 'Access Hollywood': "We haven't started the potty training yet, but it's all about the toys. The front of the bus is a big playroom, and then the bunk beds and my bed in the back, but yes they're ready."
