Loose LipsKirsten Dunst says about Justin Long: "I don't know him from Adam." Dunst must be bffs with Adam because Us has been seeing her with Justin all over the place. "On August 29, Us Weekly reports, he invited her to his $2 million L.A. home. After a sleepover, they hit the Joe Purdy show at Saint Rocke in Hermosa Beach, Calif., and lunched a day later at the Chateau Marmont, where Long, 30, got them a room." • NBC Newser Natalie Morales gave birth to a son yesterday. Luke is Morales's second son with investment consultant hubby Joe Rhodes. Congrats! • Here are some more pics of Jessica Alba and her baby daughter Honor, who is the spitting image of daddy Cash Warren! Cute. [Us, People, Dlisted]
