After years out of the studio, Hilary Duff is back with a new single, "Chasing the Sun." Duff's been promoting the single with a series of beach-themed posts on Instagram. She posed with one of the airplanes her team hired to fly across U.S. cities with a sign reading, "Hilary Duff - Chasing the Sun - July 29th!" and also posted a video of her adorable son dancing to the jam.
