Jo Whiley announced she was pregnant on her show in May
Radio 1 DJ Jo Whiley has given birth to a daughter, called Coco Lux.
The child is the 43-year-old's fourth child with husband, Virgin executive Steve Morton and weighed in at 8lbs 12oz (3.96kg) yesterday.
The couple already have a daughter called India, 16, and two sons, Jude, nine, and Cass, seven.

It's not the first baby for a DJ at Radio 1 this year.
Afternoon presenter Edith Bowman gave birth to her first child, a baby boy called Rudy Brae Bowman Smith, in June.
