One Direction star Niall Horan was so mesmerised with pop star Katy Perry's performance recently that he proposed the singer on Twitter.
The 20-year-old star, who enjoyed Perry's recent performance on 'The X Factor', complimented the 'Raor' hitmaker, reported Contactmusic.
"I love you Katy Perry! Thank you! Will u marry me?," Horan tweeted.
Perry in the 2010 season of 'The X Factor' got impressed with Horan's performance but she had suggested him to improve on his singing and his stage presence.
