Groom-to-be Spencer Pratt will make sure his bride looks like quarter-of-a-million dollars when they wed in Pasadena, California on Saturday - he has bought her a cache of stunning Neil Lane jewelry.

It was reported that the The Hills star Heidi Montag's necklaces, earrings and bracelets would be on-loan - but her generous fiancé and co-star has treated her to them, according to In Touch magazine. Montag will wear a dress designed by Monique Lhuillier when the reality TV couple exchange vows and platinum rings in a ceremony at the Westminster Presbyterian Church.

There are still questions being asked about the authenticity of the nuptials - the couple staged a commitment ceremony in Cabo San Lucas, Mexico in November and refused to make the union a legal one upon their return to America. And now sources tell In Touch that Saturday's wedding is nothing more than a phony ceremony for the series finale of The Hills.

An insider tells the publication, "It's all set up by the producers of MTV to get people to watch. It's just a plot line. They're not really getting married."

The magazine reports the wedding will be staged on a closed set with the entire The Hills cast in attendance.
