(LONDON) -- Royal author Katie Nicholl says Prince Harry has put in a guest list request to his older brother.
"Harry is said to want to have his on-again off-again girlfriend Chelsea also be given a spot at the nuptials."
Speculation over the guest list continues. Word has it Fergie will be invited to the service after all, but not to the celebrations at Buckingham Palace afterwards.
Prince Harry is set to marry Kate Middleton on April 29.
