Celebrity brand endorsements are weird. Taylor Swift got buried in kittens for Diet Coke, Katy Perry's boobs are made of Pop Chips or something and Donald Trump has his own steak. Now in honour of his own brand of tequila, Justin Timberlake has transformed... into a lime. This is completely normal.
Justin stars in a full promo for Sauza 901, his own premium brand of triple-distilled tequila, that prides itself on not needing a lime chaser. He portrays Rick Sour Vane, an anthropomorphic lime man who celebrates the rise of limes as an in-drink condiment, and suffers their fall after the release of 901. This is fine.
There's not much else we can say, other than Justin Timberlake is a lime now and we should all be very happy for him. You can watch the Sauza 901 promo below; remember, be supportive.
