FILE – In this Nov. 4, 2015 file photo, Justin Timberlake performs at the 49th annual CMA Awards in Nashville, Tenn. A watchdog group is politely pleading with Timberlake to keep his Super Bowl halftime show “safe for the children watching.” In an open letter to the entertainer issued Tuesday, Jan. 30, 2018, the Parents Television Council hopes there isn’t a repeat of what happened in 2004 when Timberlake ripped Janet Jackson’s costume to reveal her right breast.
