Kevin Federline 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.

K-Fed celebrated the big 3-0 with ex wife Shar Jackson and friends.
