On MBC's 'Radio Star' this week, CNBLUE's Yonghwa dished on MBLAQ's Lee Joon and his frugal ways.

According to Yonghwa, Lee Joon can be a bit of a cheapskate. Yonghwa said, "One day, I met up with Lee Joon and went to drink coffee, but he did not pay for himself. I paid for us both, thinking it was not much. Then we went to the skewered lamb restaurant next door where he said, 'You're paying, right?' so I paid again."

That's not all! Yonghwa said, "We were going home, and he asked for cab fare. This was after he got successful. This was not too long ago." However, he clarified that this was not an ordinary occurrence, "Truthfully, he was like that because he had lost his card."

However, it appears Lee Joon predicted Yonghwa would be revealing those incidents as Yonghwa continued, "Recently, he bought me food at a Japanese restaurant. He told me, 'I feel like you're going to say something on TV.' He asked me to also say he bought me food," making everyone laugh.
