Singer Navi revealed photos of her album jacket for her upcoming comeback album, "Hello," on January 18th. Fans were immediately able to notice her weight loss, as evidenced by her slimmer jaw line. A representative of ITM Entertainment revealed, "Navi has been preparing for this album with all her might.� She lost about 5kg through diet control and exercise for a new image transformation.� She'd always bring salads for lunch and, despite the cold, went hiking through the mountains." Navi will be releasing her digital title track and music video for her title track, "Well Done," on the 19th, followed by the full album release on the 20th. Source: Asia Today via Nate
