Nicole Curran, the wife of Golden State Warriors owner Joe Lacob, said Thursday that she received death threats on social media and even deleted her Instagram account after what some considered a less-than-cheerful reaction from Beyonce to Curran talking with Jay-Z courtside.

A brief clip showed the famous couple courtside during Wednesday night's NBA Finals game at Oracle Arena. In it, Beyonce and Jay-Z are seen smiling and waving, when Curran leans over to talk to Jay-Z. Beyonce's smile goes away as the camera cuts back to the game. The clip went viral on a number of social media sites, with Curran portrayed as upsetting the superstar singer.

Curran said she was asking Jay-Z and Beyonce if they wanted a drink, because the Warriors had invited them to the game. She told ESPN's Ramona Shelburne that Jay-Z asked for a vodka soda, and she leaned over -- into the space near Beyonce, because of the loudness of the crowd -- to ask him if he wanted a lime with it. At that point, Beyonce is seen looking serious, and then down at the floor.

"There was no hostility," Curran told Shelburne. "I was trying to be a good hostess."

She added: "I've never experienced cyber bullying like this. I can't believe our players go through this. That kids go through this."

Curran said that Beyonce and Jay-Z had been guests of hers and the Warriors three or four times in the past without incident.
