The Prince has been lined up for the first edition of Ross's new ITV chatshow, the Daily Star claims.
However, sources allegedly said that Ross has been warned not to swear or use innuendo on the show. He is also said to be banned from discussing the Prince's relationship with Chelsy Davy or the infamous Nazi costume he wore to a fancy dress party.
"Clearly Jonathan is very excited about this," an insider said. "He knows what's at stake here. The first show is going to be very special.
"Prince Harry will be the only guest. There was no way we were having him play second fiddle to a television celebrity."
An ITV source has reportedly claimed that the deal will be signed within a few weeks.
