In Sleeping With Other People, Jason Sudeikis and Alison Brie play friends without benefits, perpetual cheaters who make a pact not to get involved with each other.

"You know, I've been friends with women I've been in love with," Sudeikis told ET at a junket for the film on Thursday. "At least I would say I was. They may disagree."

In real life, the co-stars are much better off. Sudeikis and fiancee Olivia Wilde are parents to 16-month-old and Brie just got engaged to Dave Franco. But which couple will walk down the aisle first?

"Ooh, is it a race?" Sudekis said with a laugh.

"Race to the altar," Brie joked. "I'll put money on it! Who am I putting money on? Me!"

Secret weddings have become popular with A-list stars recently, as celebs strive to avoid media attention. So, would either actor consider "pulling an Aniston"?

"Absolutely," Brie told ET. "I'm like, 'Let's just elope!' That sounds like way less of a headache."

"Oh gosh. Maybe that's already happened?" Sudeikis joked. "Not to my knowledge but I should check my emails."
