Hayek says she tried not to tell her businessman husband François-Henri Pinault about the part. "I kept it a secret until I showed him the trailer," she told me at last night's Sausage Party premiere in L.A. "He was like, 'What?' I was like, 'It's not for children.' Tonight, he's going to see it for the first time."

Seth Rogen, who co-wrote the R-rated flick and stars as a hot fog named Frank, says Hayek's ex-boyfriend Edward Norton was instrumental in getting the Frida star involved after he signed on to play a Woody Allen-esque bagel. "I read the script. It was very funny. It was completely outrageous and so I said, 'Let's go!'" Hayek recalled.

Hayek's next celebration will be the party she's having for her upcoming 50th birthday on Sept. 2. She said of milestone, "Bring it on!"

Sausage Party is in theaters on Friday, Aug. 12.
