“Performing on The Voice is a heavy task for every contestant, but for Pia Renee, season 20 has been an intense emotional roller coaster.

The Chicago native returned for Knockout Rounds on Monday, but as she prepared for her powerful performance of “What the World Needs Now is Love,” she shared with coach John Legend and this season’s Mega Mentor, Snoop Dogg, why the song was so meaningful to her.

“Shortly after we got here to prepare for Battles, my mother passed away,” Pia revealed.

“My mother represented and embodied love,” the singer told the cameras, growing emotional as she explained how sad she was not to be sharing her experience on The Voice with her mom.

“So while I’m performing, I will be thinking about her.”
