Aranda has also since spoken out about coming in second place, telling Hollywood Life that he is very happy for Hardy.

"He just has to make tons of music," he shared. "And do everything to be the best that he can be.

"The whole experience was awesome," Aranda also said. "It means everything that I was able to do my own music and have people like it!"
