Lopez told radio host Ryan Seacrest on KISS-FM radio in Los Angeles that she was stunned at the results of the voting by the American public, which sent Toscano packing this week.
"Honestly, I don't know what happened," said Lopez. "(Maybe) people thought she was safe, as I did ... Maybe there was something that wasn't connecting (with the audience) that we didn't see."
People magazine said Saturday that J-Lo became choked up after the voting and went on stage to console the disappointed Toscano. "I told her to stay pure in her heart, to have faith and to know that if this wasn't the path for her that there was something bigger for her," Lopez told Seacrest.
