In the interview, she said regarding her glamorous body, "My mother is so glamorous that I inherited the gene from her.  My back muscle line is pretty, but it's a shame I can't appeal with it."

When asked if there were parts of herself she did not feel confidence in, she replied, "Of course. My stomach. Seeing as how I drink, I stated gaining weight in my stomach. It went from my most confident body part to my least confident."
