Speidi are back! Reality TV stars Heidi Montag and Spencer Pratt are hoping that a new TV show will be just the thing to smoothen out their marriage problems.

The Z-list Hills stars have made various celebrity appearances in the last few years, as well as taking part in series like Celebrity Big Brother and The View.

The new show, called Marriage Boot Camp: Reality Stars, aims to make celeb couples rethink their marriage problems and "face demons from their past that are still affecting them now, and in turn, suffocating their relationships."

Heidi and Spencer, who have been married for five years, apparently chose to appear on the show to help sort out their disagreements about having children. "Heidi desperately wants them now, while Spencer is more interested in going out and having fun," say Marriage Boot Camp's producers.

Given the fact that the couple are reportedly living in Spencer's parents house at the moment rather than the lush LA pad they shared on The Hills, we reckon the appearance on the show could be more about paying the bills than sorting out their marriage woes – but maybe we're just being cynics!

Seems like Heidi has more than just marriage issues to sort out – the star was a notable absence at ex-BFF Lauren Conrad's recent wedding, though she did take to Twitter to share her good wishes:

We hope Lauren's marriage fares better than Heidi's!
