Sorry, ladies, Jake Gyllenhaal is off the market! The veteran heartthrob, 38, who’s been unattached ever since he was linked to Ruth Wilson in 2015, is seeing 22-yearold French model Jeanne Cadieu — and their romance could be the real deal. Despite more than a decade between them, a source said that the pair, who were first spotted vacationing in Europe together in June, are a good match. Jeanne “is very mature for her age,” shared the source. “She’s a well-rounded person.” And while the twosome “took things slow” when they first met, the source adds that their relationship has blossomed into much more than a summer fling, as they’re “now pretty serious.” Ooh, la, la!
