Director Karyn Kusama had revealed earlier that Fox and Seyfried continuously laughed, making her feel like she was 'babysitting'. Fox also confessed, at a recent fan-meet for the film at the Hollywood & Highland Center, that she couldn"t stop giggling while filming the scene.
“I was constant laughing because it"s awkward and it"s strange and nobody wants to do that. Neither one of us wanted to do it so it was uncomfortable," Fox News quoted her as saying.
Fox had confirmed to Esquire magazine earlier this year that she is a bisexual.
