Rapper, composer, and producer will.i.am is currently in Korea for his 'Will I Am In Seoul' show at club ANSWER, and it looks like he has also been spending time with some of the biggest names in K-pop.

Not only is hip hop group M.I.B his opening act at his event, will.i.am also snapped a photo with Super Junior's Choi Siwon and most recently shared the above photo with CL who recently celebrated her 21st birthday.

In addition to sharing the photo via his official Twitter page, he wrote, "Pisces birthday cake for CL in seoul korea at YG's studio with 2ne1 recording..."

will.i.am and CL share the same astrological sign, as will.i.am is also a Pisces, born on March 15th.

Fans who saw the photo remarked, "aww. so sweet!", "fresh new beats and cake, what better?", and "We're so excited to see what you're going to make together!"

will.i.am has been spending more time in Korea and with 2NE1. Hopefully this means their collaboration project will drop sometime soon.
