"Brad Pitt's Cousin" is a song by American hip hop duo Macklemore & Ryan Lewis featuring American rapper Xperience from their third studio album This Unruly Mess I've Made (2016). The song was released as a single on April 12, 2016 as the third single only in Australia and New Zealand. The song was not released in the United States or Europe.
The song received mixed reviews from music critics. Killian Young of Consequence of Sound gave the album overall a 'C-', and said of "Brad Pitt's Cousin": "we have hip hop culture: the awkward interjection from God, and the awful reference to the long-expired “deez nuts” meme." Spencer Kornhaber of The Atlantic commented that Macklemore "tries to make it seem like he loves being called the actor’s ugly relative, and opens with him bragging about his cat’s Instagram followers".
