It's an "All My Children" reunion on a very special episode of "Hope and Faith," as daytime's devilish diva, Susan Lucci, gets to play opposite former co-star, Kelly Ripa.

"Extra's" cameras were rolling for the rehearsal with Rebecca Budig, Susan Flannery and Susan Lucci, as she took her shot at comedy in a sidesplitting slap-fest with Kelly.

In the hilarious episode, Kelly's character -- a former soap star -- gets a chance to return to her roots, but the plot thickens when lovely Lucci double-crosses her.

"It's like doing a Broadway play in that you have the live audience," Lucci told us about her shooting her guest shot. "They're definitely a part of it, you hear them and their response is great."

Also guesting is hunky AMC soapster Cameron Matheson, who you'll catch stripping down for action. "I've been starving myself for a week because I have to take my shirt off on this show," Cameron said. "I can't even think straight."

Catch more of Matheson, Susan and the whole big soapy "Hope & Faith" reunion on Friday.
