MBLAQ's Lee Joon appeared on the December 11 installment of SBS's 'One Night of TV Entertainment' and talked about his movie 'Rough Play' as well as his rival.

Regarding the movie, he said, "When I received the script, I was shocked to the point I got goosebumps.  I thought that if I did not do a good job, I would be greatly criticized. On the other hand, I thought that if I did well, I would get a lot of praise."

Lee Joon was then asked who his rival was and he chose IU, saying, "IU is really good at acting."  He then thought about it and said with a smile, "I filmed a bed scene.  I bet IU wouldn't be able to film a bed scene.  I filmed one," to which the show's MC said, "Good for him."
