And she is determined to show off the results of her hard work.
The 29-year-old displayed her legs and post-pregnancy curves in a short pink dress while out shopping in Beverly Hills with her fiance Wiz Khalifa on Thursday.
Amber proudly strutted along in the bubblegum-pink frock, which featured chiffon-like material across the front.
The model paired the little number with white sandals and accessorized with matching hot pink retro round sunglasses.
Amber’s multiple tattoos were prominently visible on her arms as she walked across the parking lot with her partner.
Wiz, meanwhile, was casual in black baggy shorts and a colourful T-shirt paired with black trainers and a baseball cap.
He too showed off his many tattoos, which spread all along the lower part of both his legs.
He seemed in good spirits as he flashed a peace sign for photographers as the pair left a Tom Ford store.
Amber recently revealed that she had been working out for an hour and a half these days in an effort to lose weight, after reaching 202lbs at the height of her pregnancy.
“I have a really good personal trainer,” she told E! News. “Her name is Jeanette Jenkins. Yeah, I work out every day.
“It’s hard to get off baby weight. It’s a different kind of weight because for nine months you stretch your stomach out and then it’s hard to get that back. I’m working on it. I lost like thirty-some pounds already.”
The blonde added that she gained more pounds than people think because of her relative height.
She confessed: “I was 202 pounds when I had my son. But I’m tall, so it didn’t look like it.”
