It’s been four years since the last time we heard Lil Wayne and Kendrick Lamar collaborate on Mike WiLL Made-It’s “Buy The World,” but today the pair reunited on Wayne’s long-awaited album ‘Tha Carter V.’

The project’s eighth track “Mona Lisa,” produced by Onhel and Infamous, features the two MCs spinning tales of deceptive women in their lives. They draw comparisons to Leonardo DaVinci’s famous painting Mona Lisa, which sports an ambiguous smile that they imply is hiding secrets.
