Working it! Fantasia Barrino isn't what she used to be... and that's a good thing.

The former "American Idol" winner took to Instagram over the weekend to show off three side by side images of her body, focusing on how much weight she's lost.

The girl looks as good as her voice sounds!

"The picture on the far left is during my honeymoon and I definitely gained a few pounds 😁 but with the help of @charlotteurbanskin and their medical Weightloss program I have lost the weight and I feel great!," she captioned her post. "I combined their Weightloss plan along with regular workouts with my trainer @sosonya15 and the weight just melted off! #StayUp."

The singer and Broadway star's body looks drastically different in her most recent photo, showing her body off in a tight black outfit and heels.

A week ago, she shared a collage of videos from the gym, as she prepares for an upcoming tour.

"#TheDefinitonOf ... Beast Mode!! Getting tour ready with @sosonya15. It's #RockSoul and we are not playing!!," she said.

To many of her 2.2 million Instagram followers, Fantasia's body transformation isn't news, as she often shares images of her grueling workouts with her trainer. Her trainer often shares videos and images, as well.

XPOSED... Complaining is finding faults. Wisdom is finding solutions! Sometimes, YOU need to step outside, get some air, & remind yourself of who YOU are & who YOU want to be! ***COMPLAINT FORM: please write your complaint in the box below. Write legibly ⬛️! Have a heart of praise it's far better than a mouthful of complaints. My girl @tasiasword has found many great solutions! She worked hard, prayed, persevered, changed some things, utilized her gift/raw talent on another level, etc. If YOU don't like something, change it. If YOU can't change it, CHANGE YOUR ATTITUDE... Don't complain... Kisskiss #solutions #fantasia #myclient #myfriend #lifechange #wisdom #persevere #solutions #faultsandflaws #recognize #focus #change #hardwork #Rocksoul #totalYOU #sonyaD

"My girl @tasiasword has found many great solutions!," Sonya captioned an image of her star client in a gorgeous gown in July. "She worked hard, prayed, persevered, changed some things, utilized her gift/raw talent on another level, etc. If YOU don't like something, change it. If YOU can't change it, CHANGE YOUR ATTITUDE... Don't complain... Kisskiss."

It's refreshing to see Fantasia in a good place, because it hasn't always been smoothing sailing for her.

In Aug. 2010, she admitted that she was having an affair with a married man, Antwaun Cook, and overdosed on aspirin in a suicide attempt.
