Backstreet Boys members Nick Carter and Brian Littrell have challenged Justin Timberlake and NSYNC to a five-on-five golf showdown. Littrell, a golf enthusiast with a 6.8 handicap, proposed the "Boy Band Mania Golf Tournament" during a round at Pebble Beach. While Timberlake has not responded yet, the matchup promises to be entertaining, with Carter's enthusiasm and Timberlake's golf skills in the mix. Timberlake recently revealed his battle with Lyme disease, adding a personal touch to the potential face-off between the two iconic boy bands.
