On 16 September 2007 Cox announced on her BBC Radio 1 weekend show that she was expecting her second child. Cox's last weekend show was on Sunday 17 February 2008 before she left for 6 months maternity leave. Her second child, a baby boy named Isaac, was born on 10 March 2008 weighing 7 lb 12oz, at a London hospital. She returned to Radio 1 in September 2008. Cox went on maternity leave for the third time, after her show on Sunday 7 March 2010. Less than a week later, on 12 March, she announced that she had given birth to a baby girl, named Renee, at 8:30 am GMT.
The Radio 1 DJ is thrilled after delivering a healthy 7lbs 12ozs baby boy, who she has called Isaac, on Monday. This is Sara`s first child with her advertising executive partner Ben Cyzer.
Sara`s representative told BANG Showbiz: "Mother, baby and father Ben are doing very well."
The 33-year-old star revealed she was pregnant on her radio show last September.
On 23 June 2013, Cox tweeted a picture to announce she had just been married to long-term boyfriend, Ben Cyzer.
