Federline: 'I will always be there for Britney'

Britney Spears' ex-husband Kevin Federline will "always love" his former wife and has promised to always "be there" when she needs him.

Federline, who has full custody of the former couple's two sons, insists Spears will always be important to him as she is the mother of his children, Sean Preston, two, and Jayden James, 18 months.
