Beachgoers across the country might have seen a special note in the sky from Hilary Duff on Saturday, July 26. The former Disney star, 26, took a crazy chance by promoting her upcoming single "Chasing the Sun" with an airplane message.

After sharing several shots of the messages, which read, "Hilary Duff - Chasing the Sun - July 29th," Duff tweeted a shot of herself in a bikini on the beach with her arms raised under one of the ads. 

"I swear the #chasingthesun plane is in the sky lol squint and look really hard," she captioned the picture. 

Though she was wearing a flowing, printed cover-up, Duff's toned tummy was exposed in the tiny two-piece swimsuit. 

The single mother recently signed to RCA Records, and plans to have her first album in seven years out this fall.
