The 18-year-old singer said though the song is not listed in the album but it will likely to be featured in the repackage version of his latest studio installment.

"I did a song with Lil Wayne and it's called 'Backpack', and you guys need to listen to it. It's dope," "I wanted a female rapper and I think that she is the best choice. I felt she just fit on the song (Beauty and a Beat) perfectly," he said.
