Rihanna, Swift for US music fest
Rihanna, Taylor Swift and Aerosmith have all joined the line-up for a music festival in Las Vegas.
Bon Jovi, Lil Wayne, Green Day, Miranda Lambert, Mary J Blige and Shakira are also among the big name stars set to take the stage at Clear Channel's iHeartRadio Music Festival 2012 in September.
Clear Channel, which also owns 850 terrestrial radio stations in the US, said Brad Paisley, Pitbull, Enrique Iglesias, No Doubt, Linkin Park, Jason Aldean, P!nk, deadmau5, Swedish House Mafia and Calvin Harris are also among the performers set for this year's festival on September 21 and 22 at the MGM Grand.
American Idol's Ryan Seacrest will introduce the first night's show.
He said: "Last year's iHeartRadio Music Festival had so many acts from so many different genres on one stage, a true rarity for a concert. This year it's set to be bigger and better, with an unbelievable roster of some of the most talented names in the music business."
The stellar line-up suggests the two-day marketing blitz to promote Clear Channel's iHeartRadio digital music service is on its way to repeating the success of last year's debut concert, which featured Jay-Z, Coldplay, Alicia Keys, Carrie Underwood, Steven Tyler, Rascal Flatts, Nicki Minaj and Lady Gaga, among others.
