On January 10th we revealed that Big Bang's Daesung mentioned that he had three celebrity female numbers stored on his phone. Two of them were Lee Hyori and SES Bada (Sea), but the third was a mystery. On today's Strong Heart episode he revealed that the third female celebrity is Kara's Kang Ji Young. How did he get her number? Well, it was revealed that it occurred during a video conference call on cell phones between Lee Hyori and Kara. Lee Hyori on the phone showed on the video that she was there with Daesung. Goo Hara then revealed that Kang Ji Young's ideal guy was Daesung, thats when Kang Ji Young took the phone and greeted Daesung and they exchanged numbers. After this was revealed, Daesung became a bit apprehensive on the set. Daesung stated that shortly after this video call, Kang Ji Young sent him a text message stating, "Continue to work hard filming." After Daesung received this text he said he drew the line there. He replied with "I'll work hard but that's it!" which drew a lot of laughter from the audience. Thanks to levig90 for the tip and check out the segment below:
