Singer�IU may be a superstar, but at the end of the day, she's a young girl who frets over her body image, just like other girls her age. On the upcoming episode of SBS's�'Strong Heart', IU revealed, "Now that I'm 20-years-old, I'm starting to pay more attention to my figure~" Ever the gentleman, MC Lee Seung Gi quickly complimented the star, "But your body is nice and pretty".
