Allison Iraheta, who finished fourth in last year’s American Idol behind Adam Lambert, Kris Allen and Danny Gokey, is going on tour with Lambert this summer. “I am such a fan of Allison’s music and I am so excited for her to perform it live in front of an audience,” Lambert says of her. “We have such a great brother-and-sister energy… She is pure rock and roll.” The tour is dubbed “Glam Nation Tour” and will start on June 4th in the States, making one stop in Canada on June 19th in Toronto at the Molson Amphitheatre. Also on board will be Orianthi, who played guitar on Lambert’s album and has a hit called “According to You,” which she sang during a guest appearance on American Idol earlier this year. Like Lambert and Iraheta, she’s represented by Idol producer 19 Entertainment.
