Actress Renee Zellweger and husband Kenny Chesney reportedly split because the singer refused start a family.

The 36-year-old Bridget Jones actress married Chesney four months ago (MAY05) and allegedly longed to have babies galore with the country and western singer, but he flatly refused.

A source told British newspaper The Mail on Sunday, "Her biological clock is ticking, she is desperate to have children. Renee's understanding was that Kenny wanted a family too. It was Kenny who got cold feet."
