Ever wanted to know what an adorable hamster would look like if it burst into laughter? Well, IU gave fans an idea of that image with her too-cute-for-words laughter on the set of 'You're the Best Lee Soon Shin'.

The recently unveiled still cuts of IU bursting into laughter on set show a very different image from her character in the drama, who has shed tears in every episode thus far. The singer-turned-actress has never looked happier as she acts out her scenes as a part-time worker alongside the handsome Jo Jung Suk.

IU revealed the reason for her laughter, saying, "The atmosphere on set is like the title, the best. I am always having fun filming everyday on set. I am working hard to learn from my co-stars and having a good time filming, so please look forward to Soon Shin's growth."

A representative commented, "We think the fans were not able to see enough of IU's laughter in the drama. Now as the story line evolves, viewers will be able to catch IU's laughter soon."
