Osheaga, the annual Montreal music festival, has announced its lineup for this summer's three-day festivities, which will be headlined by Outkast, Jack White and the Arctic Monkeys.

The festival released a clever poster days earlier, which revealed the entire lineup but fans had to guess who might be included based on clues within the poster.

On Tuesday, festival organizers put an end to the guessing game and revealed who would be playing between Aug. 1 and 3 at Montreal's Jean Drapeau Park.

Lorde, who won song of the year for her Royals at the 2014 Grammy Awards, will also be headlining the event.

Around the same time that single day tickets go on sale, organizers will announce on which of the three days bands will be performing.
