Petal Blossom Rainbow (I know) arrived this morning at 2.46am weighing 6lb 10oz.
The statement from the couple said:
“Both she and Jools are doing well.
“The Olivers would like to thank midwives Linda Ordish and Elaine Porter and also obstetrician William Dennis for their wonderful help and support.
“Jamie and Jools are both completely smitten with Petal already and Jamie is looking forward to two weeks paternity leave to spend quality time with his four beautiful girls.”
Petal joins her two sisters, who also have floral-themed names, Poppy Honey, 7, and Daisy Boo, 5.
