Mariah's shock weight loss

The singer stepped out recently for Karl Lagerfeld's V Magazine dinner in NYC looking literally half her usual size. 

The legendary diva dazzled in a plunging, bedazzled black dress, paired with an ornate belt that showed off her tiny waist. 

Just a couple of weeks ago, the 47-year-old made an appearance on the TV show Good Morning Britain looking very different. 

Tell us your secret, Mariah!
