LeBron James will be ringing in the new year in style. The Miami Heat’s big three — James, Chris Bosh and Dwyane Wade — will cheer the arrival of 2012 and James’ birthday at a dinner at Vesper American Brasserie at the Shelborne Hotel in South Beach. James, who turns 27 today, will be feted by 50 friends, including girlfriend Savannah Brinson. Wade’s girlfriend, Gabrielle Union, and Bosh’s wife, Adrienne Williams-Bosh, will also be on the scene. Later, the crew will head to the Shelborne’s pool for a performance by Lauryn Hill. But they’d better not get too carried away with the celebrations — they have a 6 p.m. game Sunday against the Charlotte Bobcats.
