Today Show to Speidi: Kiss Off!

It was one of our favorite celebrity feuds of the year. Sadly, there will be no rematch.

Spencer Pratt and Heidi Montag were supposed to be on Today this morning, having clashed with Al Roker the last time they appeared on the program.

This summer, Roker grilled Heidi and Spencer on their I'm a Celebrity, Get Me Out of Here shenanigans. The camps traded barbs after the fact, as well.

Hopes of another on-air confrontation were dashed when NBC pulled the plug last minute on Speidi's segment plugging their book, How to Be Famous.

"Due to a change in the show's schedule, we had to cancel the interview with Spencer and Heidi Pratt," a Today show rep said, declining to elaborate.

Translation: Al Roker pulled some strings to avoid possibly murdering them on-air.

In June, Heidi Montag said Roker made her cry with his harsh line of questioning, taking her to task and telling Spencer people think he acts like a "jerk."

"Heidi and Spencer are an interesting couple. Famous for... being infamous," he Twittered later. "Bad, vacuous behavior. We're at minute 11 of their 15."

Don't count on it, weather man. But nice work nixing their appearance today.
