Today, 2PM released the single “ Tik Tok ,” featuring actress Yoon Eun-hye , through Korean music portals. To be used in conjunction with the Cass CF , featuring 2PM members Nichkhun and Taecyeon with the fashionista, the song is about a star’s secret love. Look forward to more 2PM, as they will be releasing a new album this April.

2PM ’s Nichkhun and actress Yoon Eun-hye (Take Care of Agasshi, Coffee Prince) get it going on the dance floor and boobi-boobi dance (Korean term for “grinding”) to advertise Korean beer Cass . 2PM members are keeping busy with advertisements during their absence from variety shows . In the line of clubbing scene, Cass musical drama/advertisements ( Lee Min-ho and Jessica Gomez , Lee Min-ho and Sandara Park ), the long-legged 2PM member and fashionista Yoon Eun-hye team up as a cute and sexy couple. The commercial will be released in January 2010. You’ve told us what you think of the Taecyeon/Yoona couple. What do you think of the Nichkhun/Yoon Eun-hye couple?

Yoon Eun-hye was spotted wearing this see-through lace blouse at “ Love Your W” fundraiser on October 29th. The lace ensemble should have stayed on the runway. Who designed it? None other than, Louis Vuitton. The blouse is part of the LV winter/fall 2009 collection.
