High-flying Hollywood producer Ryan Kavanaugh will wed dancer-choreographer Britta Lazenga next week in a celebrity-packed ceremony in Capri, sources said. The two got engaged earlier this year at the Super Bowl in Dallas, where Kavanaugh popped the question to Lazenga, who’s a big Pittsburgh Steelers fan. Kavanaugh, head of Relativity Media, made his bones in Tinseltown by being a key liaison between Hollywood filmmakers and Wall Street investors, and has grown to become one of the town’s top money men. His producing credits include the upcoming “Cowboys & Aliens” with Daniel Craig and Harrison Ford and the Mark Wahlberg and Christian Bale film “The Fighter.” The wedding guest list is under wraps, but is expected to boast Hollywood power players and stars including Gerard Butler. Kavanaugh went on a bachelor party vacation in May with pals, including Leonardo DiCaprio and Bradley Cooper. Kavanaugh’s rep didn’t get back to us.
