Aston will be performing on the stage for the first time since going solo after X Factor stars JLS disbanded in 2013.
He said: "I'm so excited to be performing at V Festival for the first time, it's going to be great fun! It has definitely been tough trying to contain myself, sitting on my hands waiting to get out there with new material, so I can't wait to finally share my music with everyone...bring it on!!!"
New acts confirmed include Mark Ronson, Example, Maverick Sabre, Scouting for Girls and Bleachers.
Example is especially looking forward to performing. He said: "I can't wait to return to V Festival, the crowds never disappoint. A lot of people will be used to my shows with the live band behind me, but this time I'll be bringing DJ Wire as I want to put on a unique rave with a twist.
"I've been lucky enough to perform at festivals all over the world but there's always something special about V Festival - it feels like my home turf."
The newly announced acts will be joining a 20th anniversary line-up that includes Calvin Harris, Sam Smith, George Ezra, Ellie Goulding and more.
