‘Ally ocBeal’ actress Calista Flockhart has revealed how becoming a mum has changed her life. “I used to be a workaholic and very ambitious. I don’t know why, but it’s all melted away. I have almost zero ambition.”” Calista adopted her son Liam in 2001 and has been with partner Harrison Ford for five years now. She confesses, “I just want to go home and be with my family. Motherhood changed every fibre of my being and I think I can honestly say it brought me as close as I’ve ever come to being really happy.” “[26 June 2007]
