Duff has filed for divorce from the retired hockey player, just over a year after it was revealed that they had separated, the singer-actress' rep confirms to E! News. They have one child together, 2 1/2-year-old son Luca.
According to TMZ, Duff cited irreconcilable differences as the reason for the split. Per the filing, Duff is asking for primary custody of Luca with visitation rights for her ex.
"They remain best friends and will continue to be in each other's lives," Duff's rep said in a statement when they broke up a year ago, calling the split amicable. "They are dedicated to loving and parenting their amazing son, and ask for privacy at this time."
