As baby names go, it's certainly original.

James and Jools Oliver have announced that their fifth child is to be named River Rocket Oliver.

The boy joins Poppy Honey Rosie, 14, Daisy Boo Pamela, 12, Petal Blossom Rainbow, six, and Buddy Bear Maurice, six, in the Oliver clan.

There have been suggestions that their newborn was named in tribute to the River Cafe which helped propel the chef to fame.

Whatever the reasons, they are far from the first high-profile couple to share a weakness for bizarre baby names.
