Yesterday was a special one for both Olivia and Jessica. It's Olivia's first Valentine's Day after getting engaged to Jason Sudeikis, and she certainly had romance on her mind. She tweeted, "90% of people get laid on Valentine's Day. The other 10% get cards. Good luck." Jessica, meanwhile, has a new guy in her life. Jessica Chastain's dating Gian Luca Passi de Preposulo, an executive at Moncler, according to reports.
