Lady Gaga's Sunday performance in South Korean capital Seoul sparked controversy in the country, with hundreds of conservative Christians praying against the concert, accusing Gaga of 'advocating homosexuality and pornography'.

Her appearance in the country has caused uproar among religious groups who disagree with Lady Gaga's support of gay rights, with posters last week appearing in Seoul slamming Gaga's 'lewd lyrics and performances'.

“We will pray to God that the concert will not be realised so that homosexuality and pornography will not spread around the country,” said organiser Kang Ju-Hyun.

Under 18s were banned from attending the concert, after the local Media Rating Board rated the concert unsuitable for young fans.

A statement from the Korean Association of Church Communication is said to have stated: "Our Christian community needs concerted action to stop young people from being infected with homosexuality and pornography," ahead of her arrival in Korea.
