"She and Jools are doing well," his rep tells Us.

Oliver posted updates and hospital photos on Twitter right after the birth.

"She's so cute," he wrote, adding that her name "goes well" with their two daughters, Poppy Honey, 6, and Daisy Boo, 5.

An expert explains what celeb baby names mean.

"The Olivers would like to thank midwives Linda Ordish and Elaine Porter and also obstetrician William Dennis for their wonderful help and support," his rep tells Us. "Jamie and Jools are both completely smitten with Petal already and Jamie is looking forward to two weeks paternity leave to spend time with his four beautiful girls."

The couple -- who have been married for eight years -- didn't know the baby's sex beforehand.
