British singer Natasha Hamilton has split from her husband after six years of marriage. The Atomic Kitten star has decided to part ways from former model Riad Erraji after the pair fell "out of love", and she insists the hardest part of the split was telling their three-year-old son Alfie and Hamilton's two kids from a previous relationship. She tells Britain's Sunday Mirror, "When I took my wedding vows I thought it would be forever but somehow over the last year we have just fallen out of love and, no matter how hard we try, we can't get it back... "We've just grown apart - and that's the devastating thing... I'm just so incredibly sad." Hamilton has poured her heart out to her bandmates Kerry Katona and Liz McClarnon, who are helping her through the painful split. She adds, "They're being really supportive, texting and calling me to make sure I'm okay. They can't offer any advice because they're not in my relationship but they've been there for me." The pair wed in Cheshire, England in 2007.
