The golden couple of show business, Nicholas Tse Ting-fung and Cecilia Cheung Pak-chi, are to end their troubled five-year marriage. After months of rumours, Cheung's management company, Asia Entertainment Group, issued a statement on Monday on behalf of the couple. 'We have decided to file for divorce because of our irreconcilable differences,' it said. '[We] have reached an agreement peacefully.' The couple have two sons: Lucas, four, and Quintus, one. 'We will raise our two children together,' the statement said. The relationship between Tse, who was crowned best actor at the Hong Kong Film Awards this year, and fellow award-winner Cheung has been one of the most discussed showbiz love tales. Tse, 30 (above with Cheung), was dating Canto-pop diva Faye Wong when he became involved with Cheung, 31, a decade ago. The couple would go on to have a rocky relationship marked by several high-profile scandals.
