Celebrity fever gripped the city last night as some of the world's biggest pop stars attended the first part of a two-day wedding between Hong Kong-born singer Coco Lee and Bruce Rockowitz, president and chief executive of Li & Fung. In what would easily be one of the most lavish weddings to take place in the city in years, the nuptials between the 36-year-old beauty and her Canadian partner of eight years set off a flurry of activity at the Ritz-Carlton hotel in Tsim Sha Tsui. Onlookers camped outside for days to catch a glimpse of the celebrity guests, which reportedly included Oprah Winfrey, Beyonce and Jennifer Lopez. Last night, Lee's management confirmed that a private ceremony was held at the Sky100 bar on the 100th floor of the International Commerce Centre, the tallest building in the city, but could not say who had attended. Lee, also known as Ferren Lee, and Rockowitz, 52, first met in Hong Kong in 2003 and were engaged in 2005. The singer reportedly took a year off work to plan the wedding, estimated to cost more than HK$100 million. About 200 people, mainly close family and friends, including American fashion designer Tommy Hilfiger, attended the 30-minute ceremony, before continuing to a dinner and show at the hotel. 'There will be very big international acts and some of the hottest US artists performing tonight and tomorrow,' a spokeswoman for Lee said yesterday. 'Coco wore a dress by Vera Wang because she's a very good friend of the couple.' Guests were reportedly flown in by helicopter, and the hotel confirmed that all the luxury suites, 80 in total, were fully booked yesterday and today. The wedding celebrations will continue tonight with a party at Shaw Studios in Tseung Kwan O, where a red carpet will be rolled out as guests arrive for the evening. The complex has one of the biggest soundstages in Asia and several banquet halls, but it is uncertain where the wedding party will take place. Lee's management said about 800 guests were expected at tonight's event but could not confirm exact numbers or the international guests. Born in Hong Kong, Lee moved to the US when she was a child. She studied biology before turning to singing. Lee, who sings in English, Cantonese and Putonghua, released her first album in English in 1995, and over the years, she has gained a big fan base in Taiwan.
