The Big Bang Theory is preparing for Howard and Bernadette's nerdy nuptials, but will the bride catch cold feet? Nancy O'Dell visited the set retrieving clues as to how the upcoming wedding episode might pan out.

"I could be a runaway bride; I could not be," said Melissa Rauch (who plays Bernadette).

Melissa's character contemplating a wedding cancellation could spell disappointment for Howard (played by Simon Helberg), who already has enough bad news in tonight's episode when it's revealed that his space launch is off.

We'll have to wait until next Thursday, May 10, to see how the wedding works out, but you can still catch an all-new episode tonight at 8/7c on CBS.
