LOS ANGELES—Fueling rumors that the 49-year-old star was finally settling down, Leonardo DiCaprio was spotted with girlfriend Vittoria Ceretti on Thursday as she flaunted a new nondisclosure agreement. “Oh, man, you can tell he spent a lot on that thing,” said one Hollywood insider, who added that the 25-year-old Italian model looked “absolutely ravishing” in the paparazzi photographs that captured her showing off the ironclad confidentiality contract in her left hand. “Just look at it! It’s huge and absolutely stunning. I mean, that NDA must be dozens of pages. I bet the sheen of all that paper really sparkles in the sunlight.” At press time, swooning sources stated that you could tell DiCaprio must really not love her.
