Talk about marketing! Hilary Duff sent airplane messages in the sky to promote her upcoming single, "Chasing the Sun".
She posted an Instagram picture on Saturday in a bikini with the caption, "I swear the #chasingthesun plane is in the sky lol squint and look really hard."
She even posted a list of where the "surprise airplanes" flew over to give fair warning.
The former Dsiney star signed with RCA Records and is releasing a new album this fall. This will be her first album in seven years.
Before the airplane promotional strategy, she sent out this Instagram letting her followers know that you can pre-order her new single.
