ADD TALK-SHOW host to the job titles held by Knicks guard and discount sneaker entrepreneur Stephon Marbury. Stars on Stars premiered on Fox Sports Net on March 9, with Marbury lobbing softball questions at Kobe Bryant. The first episode of the half-hour-long, weekly series drew 75,000 viewers, a 0.1 rating, but Marbury has at least one enthusiastic fan. Bryant called Stars, "the best show I've ever done." ... Laila Ali's Dancing with the Stars experience—she debuted on the show on Monday—may come in handy in July, when she marries former NFL receiver Curtis Conway, 36. The couple announced their engagement last week. "I told him, 'You know everyone's going to expect us to cut a rug for our first dance,'" the 29-year-old women's super middleweight champ (above), said. "He's going to have to take a couple of lessons." ... Daisuke Matsuzaka is already on a roll. FuGaKyu, a sushi restaurant in the Boston neighborhood where the Red Sox righthander will live, has introduced the Matsuzaka Roll: Matsutake mushrooms, asparagus, lobster and avocado. The roll can be washed down with a Matsuzaka Martini, made with vanilla vodka.
