Tom Cruise and Katie Holmes have sensationally revealed they are divorcing after five years of marriage.The Hollywood superstar, 49, said he was ‘deeply saddened’ that his younger wife, 33, had filed for a separation.He revealed the former Dawson’s Creek actress had initiated the split, bringing a dramatic end to one of Hollywood’s most high-profile romances. In a surprise move, Miss Holmes is understood to have filed for sole custody of the couple’s daughter Suri, six. This is a personal and private matter for Katie and her family,’ Holmes’s lawyer Jonathan Wolfe said in a statement to People magazine.  ‘Katie’s primary concern remains, as it always has been, her daughter’s best interest.’A spokesperson for Cruise, who is currently in Iceland filming his new sci-fi movie Oblivion, said: ‘Kate has filed for divorce and Tom is deeply saddened and is concentrating on his three children.’The actress filed documents in New York this week citing ‘irreconcilable differences’.She has asked for legal custody, primary residential custody and a ‘suitable amount’ of child support from her husband, TMZ reports. Miss Holmes is also asking for a division of property in the divorce documents, although there is a significant pre-nuptial agreement that is based on California law. The couple are worth around $275 million - much of that owing to Tom’s box office success. The terms of the pre-nup are understood to be clear - for each year the couple stay married, the Dawson’s Creek actress collects $3million - to a maximum of $33 million after 11 years - as well as their palatial home in California.If their marriage had lasted more than 11 years, Holmes would have received half of Cruises’s reportedly $250 million fortune.After filing for divorce less than six years later, according to the agreement, Katie should only be entitled to $15 million as well as the couple’s $35 million Beverly Hills MansionBut with an estate worth upwards of $275 million, Katie is expected to seek much more and there is already intense speculation as to how much she will collect when the papers are signed.Cruise is believed to have ‘not seen’ the divorce coming.But sources insist that she did tell her husband of five-and-a-half years that she was filing for divorce – but she didn’t give him a chance to control the spread of the news, as he did with Nicole Kidman. The fact that she issued a solo statement speaks of some heat around the final extinguishing of the marriage.The pair have not been seen together in public for almost three months - they were last pictured on April 5 while in Baton Rouge, Louisiana.Miss Holmes failed to turn up to at any of the worldwide premieres of her husband’s latest film Rock of Ages, despite Cruise’s constant protestations of love for his wife.The final arguments seem to have been over where Cruise was going to spend his 50th birthday on Tuesday. He told her that he was planning to be on the set of his latest film Oblivion, in Iceland, and that seems to have been the last straw.The statuesque brunette had frequently been pictured looking drawn and exhausted during her marriage. One Hollywood source said she had been ‘utterly miserable with Tom for months, if not years.dailymail.co.uk
