SEOUL: US pop diva Lady Gaga is slated to perform at a summer music festival in South Korea, where her first show two years ago received an adult-only rating from state censors.

The festival, to be held at Seoul’s Olympic stadium on August 15-16, will feature a host of K-pop stars including “Gangnam Style” rapper Psy, the YG entertainment agency said.

Lady Gaga will appear on the second day of the festival, to be co-hosted by YG and a local music production agency.

When the 28-year-old singer last performed in Seoul in April 2012, religious groups called for the concert to be canceled on the grounds that she advocated obscenity.

The show went ahead — but only after a state ratings board judged it unsuitable for younger audiences, prompting a ban on under-18 fans.

It was not immediately clear if her show at this year’s festival would be subject to similar restrictions.

“It’s too early to say because we have yet to see the contents and details of her concert here,” a spokeswoman for the state rating board told AFP.
