The "American Hustle" actress was starstruck when meeting Damian Lewis -- and learns of his "Homeland" character's demise.

A few things celebrities usually expect when walking an awards-show red carpet: chatting through countless interviews, greeting other actors, waving to superfans who pay $4,200 each to wave back from bleachers.

Not on the list? Getting one of your favorite shows spoiled.

While on the Access Hollywood platform during Sunday night's Screen Actors Guild awards, Jennifer Lawrence found herself starstruck when standing only a few feet away from Damien Lewis of Homeland.

"That is Brody, I've never met him before -- stop it!" she screamed as she turned away, when Lewis leaned over to greet her. The Showtime actor than said, "Let's cuddle," and gave her a hug. "You're so great, the show's amazing, my ears are so red!" she told him.

As the two actors were chatting, a reporter chimed in: "Are you upset that he died?" she asked Lawrence, referring to the death of Lewis' Nicholas Brody on the season three finale.

"What? I can't process this right now, there's cameras, I can't believe you said that," said a nearly teary-eyed Lawrence, who has only watched Homeland through season two. "I have to wait for it to come out on DVDs because I'm not patient ... I'm past mad, it's this weird other emotion. I feel like my heart just fell out."
