The pop artist was in Korea back in 2009 and Lee Jung Hyun had opened up for her concert. On MBC FM4U's 'Two O' Clock Date With Park Kyung Lim', Lee Jung Hyun was asked about her connection to Lady Gaga.
"I stood on Lady Gaga's concert opening stage after Lady Gaga asked me to do so. She told me that she wanted to see my stage up front and center, but she couldn't because of the fans in the stands. She's younger than me, and I'm a big fan of hers."
