Singer-songwriter Kelly Clarkson has been famous since the 2000s, when she skyrocketed to the top of the charts after winning American Idol. The songstress, who has two kids with her former manager, Brandon Blackstock, usually takes security with her and her family to fend off paparazzi and crazy fans.

However, Clarkson found herself on the opposite end of that when Rob Gronkowski, an NFL tight end and notorious prankster, played a prank on her at an awards ceremony. Gronk pretended to be a bodyguard, “bouncing” Clarkson out of her seat to make way for Florida Georgia Line at the BBMAs.
