A few new performers have been picked up for Glam Nation and Adam Lambert.

Last year’s runner-up in the “American Idol” competition has dates set for his summer tour. Two opening acts have also been added: Orianthi, singer-guitarist, who made two appearances this season on “Idol,” and Allison Iraheta, fellow “American Idol” finalist.

On June 4, “Glam Nation Tour” is set to kick off in Wilkes-Barre, PA. It will then visit medium sized venues in the eastern US as well as one visit to Canada during the months of June and July. On July 27 and 28 the only stop on the West Coast will occur when the tour performs at Orange County Fair for a two night stand. The outing will conclude on September 18 in St. Petersburg, FL at Tropicana Field, the biggest venue on the tour.

Iraheta and Lambert have performed together before on the “American Idol” tour last summer, and a show in February where they were on stage with Idol winner Kris Allen. Lambert said I’m a big Allison music fan. I’m very excited she will be performing live for audiences. Allison is all rock and roll. We have fantastic brother-sister energy.

Orianthi, who along with Iraheta and Lambert, is represented by 19 Entertainment, “Idol” producer, played guitar on Lambert’s album on the song “Sleepwalker.” She also has her own hit single “According to You.” Earlier this season, Orianthi performed on Idol’s result show and was in the backing band for Mary J Blige for”Idol Gives Back.”
