Jessica Simpson lost a HUGE amount of weight

Over the past years, Jessica Simpson had to deal with a couple of extra pounds, but she left everything behind and looks completely transformed!

The singer – and also an entrepreneur – wanted to show the entire world how good she looks now, by flaunting a black dress, while going out in New York City.

This is what we’re talking about:

Jessica Simpson revealed that after giving birth to daughter Birdie Mae, back in May, she dropped almost 100 pounds.

“6 months. 100 pounds down. (Yes, I tipped the scales at 240),” she wrote on social media.

“My first trip away from #BIRDIEMAE and emotional for many reasons, but so proud to feel like myself again,” she continued.

This is the result of serious working-out sessions, as well as dieting, as Jessica revealed!
