Amber Rose was a vision Sunday night at the 56th Annual Grammy Awards in a stunning gold dress that showed off her incredible weight loss. Just last year at the awards show, the model was nine months pregnant.

On Instagram, after the Grammy Awards, Rose shared a photo showing the drastic change in her weight since last year at the Grammys, when she had a huge baby bump. “I can’t believe I was 9 months pregnant last Grammys! This year I’m a mommy and officially a Wife. God is good all the time. Amen,” her photo caption read. Also noticeably different were Rose' arms, which were covered in makeup to hide her numerous tattoos for the big night. Amber Rose Amber Rose shared this "before" and "after" photo Photo: Instagram

It is clear that Rose has been working out and eating healthily. She recently admitted she weighed 202 pounds at the peak of her pregnancy, though most people were unable to tell because of her height -- she tops 5'7". She worked out for an hour and a half each day with celebrity trainer Jeanette Jenkins to lose the extra weight, and she said it was no easy feat to drop the pounds.

"It took me like a year to lose the weight," Rose told E! on Sunday. "I did it the natural way, so I just tried to eat right. I'm a Philly girl, so I grew up on Philly cheesesteaks and stuff like that. But yeah, [I've been] just trying to eat right and exercise and it finally came off."

In November, Rose posted a picture illustrating her weight loss with the caption, “I'm almost at my goal weight. Just 7 pounds to go! Absolutely no surgery, just diet & exercise. Most celebs give u false hope when u have a baby (My son was 9lbs) and in 3 months ur supposed to be skinny again.... It's not realistic in most cases. It takes 6 weeks to heal before u could even work out. Anyway, the moral of the story is losing baby weight the natural way takes longer but it's much healthier for ur body and helps u stay strong to carry another baby. So don't put ur life at risk for societies standards of when ur suppose to lose ur pregnancy weight. Take ur time & don't take the easy way out [sic]– Muva”

She may have been indirectly speaking about Kim Kardashian, who began showing off her weight loss three months after giving birth to North West. Rose dated Kanye West, Kardashian’s fiancé, before he ended up with Kim, and Rose accused Kardashian of cheating on then-boyfriend Reggie Bush with West.
