CANCER-stricken Michael Douglas and his wife Catherine Zeta-Jones have been named the top celebrity couple of 2010. The Wall Street legend dominated headlines in August this year when he revealed he had been diagnosed with a throat tumour. Zeta-Jones has been a constant support to her husband of 10 years during his health battle - and theyve topped a poll by dating website to find the favourite showbiz couple of the year. Angelina Jolie and Brad Pitt came second, while Demi Moore and Ashton Kutcher rounded out the top three of the list. Contactmusic
