is sending "good energy" to ex-wife Britney Spears.
Kevin, who has two children with Britney, says the troubled singer is a big part of his life and hopes she gets her life back on track soon.
The 30-year-old, who also has two children with former lover Shar Jackson, said: "I will always love the mothers of my children, and I will always be there for both of them. I believe that any good energy I put out there brings more good energy into my own life. The relationships
with my kids
and family will last my whole life and are the most important to me.
"It is so very important to me that my children will always know and never question, that no matter what happens, they have a mommy and daddy who love them very much."
Kevin, who was recently named Father of the Year by Details magazine, also revealed he considers his children to be the most important thing in his life.
He added to In Touch Weekly magazine: "I spend most of the day chasing my kids around the house. Their needs define my schedule every day.
"I'm going to be the best role model for my kids. And if that example helps other young, single dads who might be going through the same experiences that I am right now, it would be a great compliment."
Kevin has been fighting Britney for custody of two-year-old Sean Preston and 18-month-old Jayden James since last year.
He also has a five-year-old daughter Kori and a three-year-old son Kaleb, from his relationship with Shar.
