Jay Z got lost in the moment, emotionally belting out lyrics to one of his wife's mega-songs.
Jay was standing with Nick Jonas, watching Beyonce perform "1 + 1" Saturday at the Budweiser Made in America Concert in Philly.
He wasn't the only 1 caught up in the moment. Beyonce's mom Tina Knowles and Kelly Rowland joined in as well.
Who knew Jay and Nick were buds.
