This is a name that starts off OK and then gets worse as you move along it. Petal Rainbow Blossom Oliver is the daughter of British celebrity chef Jamie Oliver and his wife, Juliette. If you think her name is bad, you should meet her siblings - Poppy Honey Rosie, Daisy Boo Pamela, Buddy Bear Maurice, and River Rocket Blue Dallas.
Petal is barely ten years old, and so it's unknown how she feels about her name just yet. It's quite a departure from the type of naming strategy that her father's parents went for, with 'Jamie Oliver' being about as normal as normal names get. Perhaps that's what inspired the much-admired cook to go with something as outlandish as possible when the time came for him to have children of his own. Or maybe he and his wife just really like flowers!
