Pop-Tarts, a Kellogg brand, is celebrating its 50th birthday by announcing the return of Crazy Good Summer, its annual concert series. Produced by Live Nation Entertainment, the lineup will feature free performances by Demi Lovato, Emblem3 and Jasmine, as well as a private concert by Austin Mahone for one winner of the Crazy Good Summer sweepstakes.

The Crazy Good Summer birthday bash kicks off Wednesday, June 25, when Jasmine V takes the stage at the Los Angeles House of Blues. Starting June 16, fans ages 13 and older can visit the Pop-Tarts Tumblr page to RSVP and get free tickets.

Demi Lovato and Emblem3 will each give free concerts in July and August. Fans can visit PopTartsCrazyGood.com throughout the summer for clues on the surprise locations and dates and for more free concert tickets.

To help celebrate Pop-Tarts' big birthday and wrap up the 2014 concert series, Crazy Good Summer alum and teen heartthrob Austin Mahone is giving one lucky fan a chance to win a free, private concert for his or her high school. Until July 31, 2014, teens can visit KelloggsFamilyRewards.com/CrazyGoodSummer to enter for a chance to win the Crazy Good Summer sweepstakes. The winner will be announced in August on the Pop-Tarts Tumblr page.
