이효리 - U-Go-Girl (With. 낯선)

Lee Hyori (Korean: 이효리) (born May 10, 1979) is a South Korean R&B & hip-hop singer and actress. She started off as part of the successful K-pop girl group Fin.K.L, but has since become a solo artist. Her first album was very successful, winning many "Daesangs" (a Korean award equivalent to "Artist of the Year") for that album. She has since become the highest-paid female singer in South Korea.

Almost two years after her previous album, Lee returned with H-Logic on April 13, 2010. The album has 14 tracks, including a collaboration with Daesung from Big Bang, 4Minute's Ji Yoon, After School's Bekah, Gary from Leessang, and Sang Chu from Mighty Mouth. The singer also worked with E-Tribe, the team behind "U-Go-Girl", the lead single from her previous album.
