Starting as early as mid-April, the mega K-Pop stars are making their returns back to the scene. First in line is no other than world sensation PSY, who will release "Gentleman" on April 12.

Lee Hyori, who has been dubbed a social entertainer for her extended participation in various social works, is coming back to K-Pop for the first time since 2010. With rapper Beenzino featuring in her album, fans are wondering in great anticipation what the queen of K-Pop will show.

Nicknamed beastly idols, 2PM will be releasing a new album for the first time in two years. Having spent much of their time overseas performing concerts, 2PM is scheduled to release their new album this May. JYP Entertainment has held nothing back with advertisements, airing their trailers over 70 times in New York Times Square and London.

2PM is also preparing for the final concert in Korea which will conclude their Asia Tour. On June 21 and 22, they will hold the 'What Time Is It?' concert in Seoul.

T-ARA is also coming back with a new song. With their first-ever unit group of Eunjung, Hyomin, Jiyeon and Ahreum, they will release their song, "Countryside Diaries" on May 1 and return to K-Pop. This song is reported to be an up-tempo dance song.

Meanwhile, Rainbow, A Pink, Dalshabet and Nine Muses are also aiming to make their comebacks before the end of 2013. With many of the key players of K-Pop returning to the scene, we have many more great music and performances in store for the rest of the year.
