Actress Demi Moore is seeking alimony from estranged husband Ashton Kutcher, according to divorce documents filed in a Los Angeles court. Requesting financial support from Kutcher,35, is an unusual move for Moore, 50, who was one of the top female earners in Hollywood during the 1990s. Her court filing did not specify an amount sought. Moore began dating Kutcher a few years after her split from actor-husband Bruce Willis. Their relationship became tabloid fodder due to their 16-year age gap, and the couple married in September 2005.
