There will be a star-studded wedding party tonight at the Wolffer Estate in Sagaponack for Brooklyn Nets and Barclays Center CEO Brett Yormark and bride, Elaina Scotto, sister of “Good Day New York” anchor Rosanna. Those expected include Matt Lauer, Katie Couric, Jason Kidd, Michael Strahan, Bruce Ratner and Town broker Jonathan Cohen. The newlyweds had a small private ceremony at the St. Regis last week. There’s lots to celebrate, since Yormark and Ratner’s group was just picked to renovate Nassau Coliseum.
