Growing up in Southern California, America-born Korean teen star Megan Lee was never weight-conscious. But now that the YouTube cover queen wants to give stardom a shot in Korea, she is watching what she eats very closely.

"No more pizzas," lamented the 16-year-old, who was in Singapore to perform at the second edition of Men's Fashion Week at Marina Bay Sands.

The former star of American TV series like Crash (2008) and Disney Get Connected (2008), moved to Korea a few months ago to take part in televised singing contest MBC Star Audition. Performing on live television was not her biggest challenge. Speaking in Korean and slimming down for the camera were.

The teenage vocal powerhouse, who has more than 100,000 subscribers to her official YouTube channel, said she started going on diet after seeing how chubby she looked on Korean TV compared to her slimmer counterparts.

She has since dropped a dress size, but will she also consider going under the knife to get that instant picture-perfect look? The sweet-mannered girl shared all on RazorTV.
