At least, that's what Katy Perry has been up to in a new Postmates advertisement, which features the songstress, John Legend, Snoop Dogg, Shawn Mendes and more revealing their favorite local restaurants. "Lean in to those cravings, because I am," Perry tells the camera after shouting out vegan hotspot Crossroads Kitchen in Los Angeles. The snippet is part of Postmates’ #OrderLocal campaign, which encourages users to support small businesses amid COVID-19 shutdowns.
