Cassie shows off body transformation 7 months after giving birth

Cassie is showing off the results of her hard work after giving birth to daughter Frankie.

“I haven’t posted anything like this in a while, but I’m very proud of myself,” Cassie wrote on her Instagram stories. “The female body is truly an amazing thing. I didn’t rush to lose weight after having Frankie in December, but when I was ready to I struggled with it for some months.”

The “Me & U” singer, 33, said she only saw success when she stopped putting so much pressure on herself.

“… and with less stress and healthier habits this is me 7 months postpartum. Feeling really good, I’m healthy and working on my strength. Love your body!!!”

Cassie then posted a video and a photo of herself wearing a lacy yellow bra and unbuttoned jeans that highlighted her transformation.

It’s unclear if her celebrity-trainer husband, Alex Fine, helped her with her fitness.
