Singer Ricky Martin is grateful to have children who are "warriors" because his twin boys have adapted well to life on the road with their busy dad.

The Livin' La Vida Loca hitmaker insists on travelling the world with his sons Matteo and Valentino because he struggles to focus on work when they are apart, and he is adamant his kids feel the same when they have to stay at home with grandma.

Martin tells Billboard.com, "I can't (leave them behind) - I don't work well without them. They're stuck to me constantly. If I'm in L.A. (Los Angeles) and have to travel to Hong Kong for 24 hours, I'll leave them with my mum.

"But fortunately, I have sons who are warriors and who were born on tour and don't know anything else. They're road babies. Some people say, 'Ricky, your kids need stability,' and I say, 'I'm their stability. They feel unstable if I'm not there.'"

And the single dad reveals he uses his sons' reactions to his new material to determine if a song is worthy of becoming a single.

He says, "I press play and watch their reaction. Disparo al Corazon is the second single off the new album, and it's a song one of them wouldn't stop singing. So maybe the boys influenced the choice of single."

However, Martin admits it hasn't been easy juggling recording commitments for his new Spanish-language album, A Quien Quiera Escuchar (To Whomever Wants to Listen), with parenting and touring duties.

The 43 year old, who also serves as a judge on reality shows The Voice Australia and The Voice Mexico, explains, "We recorded on four different continents. The moment we'd finish a song, we'd run into the studio because there simply wasn't a chunk of time available."

Matteo and Valentino were born via a surrogate mother in August, 2008.
