(( British royal Prince William reportedly had a commitment ceremony with his on/off girlfriend Kate Middleton while on vacation in paradise, according to sensational press reports.

The Globe claims Prince William, 25, heir to the U.K. throne set up a mock wedding ceremony as a surprise to Middleton during a vacation in the Seychelles.

The alleged semi-nuptials were so last minute, William didn’t have time to buy Middleton a ring and instead used a red leather band bought from a local beach trader to seal his commitment.

William wore shorts and a T-shirt, while Middleton donned a sarong.

Insiders claim the beach affair was more of a commitment ceremony than a full-blown marriage ceremony — and they doubt that William and Kate are officially husband and wife, even though a local preacher oversaw the nuptials before two witnesses.

A source tells the Globe, “This was the moment that William committed himself to Kate — forever. He told her that he would love and protect her for the rest of his life.”
