The Thrills and McFly have been added to the V Festival line-up taking place in Chelmsford and Staffordshire.
Irish band the Thrills will release their third album Teenager this year and will play V after four and a half years of touring the globe.
McFly are the customary pop act added to the festival line-up to bring about a bi-polar character, contrasting with the likes of Foo Fighters and the Happy Mondays.
Bob Angus, V festival director, said: "In my mind, the perfect festival features a wide range of acts and this year I'm certain we've achieved that.
"A line-up featuring artists that range from Foo Fighters to McFly is just what you want; it appeals to everyone. I'm incredibly pleased with the way this year's V Festival is shaping up, and we've still got another great announcement up our sleeves."
Also added to the line-up are Rilo Kelly, Glen Tilbrook and the Fluffers and the Hours, who will take to the stage along with the 46 other confirmed acts this summer.
The line-up now comprises The Killers, Kasabian, The Kooks, Amy Winehouse and Manic Street Preachers as well as Kanye West and the Fratellis.
Primal Scream will also play at the festival along with Babyshambles, The Coral, Lily Allen, Editors and Jarvis Cocker.
