Hilary Duff spent Saturday at the beach but it wasn't just another lazy summer day for her. The 26-year-old star took to the beach to check out one of the many planes that flew around beaches across the country advertising her forthcoming new single, 'Chasing the Sun,' which will be available for purchase on Tuesday, July 29.

Duff wore a floral patterned swimsuit along with a matching outer cover. "I swear the #chasingthesun plane is in the sky lol squint and look really hard," she wrote in the caption of the photo.

Earlier in the day, Duff announced that several planes would be flying over various beaches with 'Chasing the Sun' banners. Some of the cities included Los Angeles, New York City, Miami, Chicago, San Diego and Houston.

She then shared various fan-submitted photos from around the country.

'Chasing the Sun' will be the first single off Duff's upcoming album, her first since 2007's 'Dignity.'
