Lively apparently got that conversation out of the way before her latest thriller, All I See Is You. The star appeared nude in the movie for the first time, after insisting that nudity can be "distracting." She definitely ran that by hubby Reynolds before filming that scene. "It's helpful to know when you're acting that you're in a relationship with someone else, that [sex is] not what's actually happening," Lively explains. "Because I have friends who aren't married to someone who's in the business, so they're like: "Oh, so you're not actually making love in that scene?!" And I'm like: "No, no, no, no, definitely no.'" It's Hollywood, not xHamster! Sex on screen is totally simulated, and the work to get across a convincing scene can be super awkward. And if it seems like the sex is real, as Lively's friend seem to think, that means the actors are doing something right.
