Shawn Mendes just celebrated his 21st birthday this week, and we want YOU to celebrate WITH Shawn. Like... WITH Shawn Mendes backstage at his concert.

Yeah, we’re giving you the chance to win tickets and backstage passes to hang out with the superstar later this month in Philadelphia.

All you have to do is open the PST app and share a birthday greeting for Shawn. Then you’ll be qualified to win tickets to the show AND backstage passes to meet Shawn.

Just open the PST app and tap on the button for “SHAWN'S BIRTHDAY.” Then submit a photo, video or audio greeting for Shawn wishing him a happy birthday. We’ll randomly pick one lucky entry to win our awesome prize.

You HAVE to hurry though, this contest is ONLY available this weekend (August 9-11).

By the way, our winner will receive:

A pair tickets to see Shawn Mendes at the Wells Fargo Center in Philly on August 28. The show will feature special guest Alessia Cara as well. Of course… as if that’s not cool enough, we’ll also hook the lucky winner up with two passes to meet Shawn before the show. Yeah, how awesome is that?

Entries must be submitted on the PST app before 6 am on Monday, August 12, 2019. WPST's standard contest rules apply. The winning birthday greeting will randomly be selected from all submissions.
