Listen to One Direction on iHeartRadio

One Direction is giving fans plenty to look forward to this month.  Their new single "Best Song Ever" isn't due out until July 22nd, but the boys' label boss and mentor Simon Cowell is already singing its praises. 

On Monday, he tweeted that he'd seen the yet-to-be released video for the song, declaring it "their best video ever."  He added, "these boys are very very smart. 

The British boyband, whose "Take Me Home" tour heads to East Rutherford, New Jersey and Hershey, Pennslyvania this week, are also continuing their efforts to interact with fans. They've asked their 13 million followers to design and send in a cover for "Best Song Ever," promising to pick one to use as the official album art.  Footage directly from fans will also be used in their upcoming concert documentary "This Is Us," which hits theaters on August 30th.
