Young country stars Jessica Andrews and Billy Gilman will host the seventh annual Sizzlin’ Country concert on May 8 on the Laramie Street set of Warner Bros. Studios in Burbank, Calif. The show benefits the Cystic Fibrosis Foundation and will feature country artists who will be on the West Coast for the Academy of Country Music Awards, taking place May 9. The lineup has not been announced. Artist manager Scott Siman, whose clients include Andrews, Gilman and Tim McGraw, will be honored with the Heart of Country Award for his contributions to the cystic fibrosis initiative. The six previous Sizzlin’ Country concerts have brought in more than $1.7 million for cystic fibrosis research and care programs. Andrews and Gilman will tour the U.S. together beginning after Fan Fair in June.
