Get it, girl!

Briana Renee took to Instagram to show off her impressive post-baby weight loss — and revealed that she’s almost completely back to her pre-baby weight. The Little Women LA star took a sexy selfie to show off her amazing results.

“70 lbs. Lost more than my Mavi weight, and I'm 1 lb away from my best,” the 33-year-old wrote in the caption, then added the flexed bicep emoji.

Fans congratulated the mom-of-two, who proudly flaunted her toned arms, trimmed waist and sexy curves in a black onesie. One fan said that she was jealous of Briana’s progress, and many of them cheered her on and told her to keep up the good work.

Briana gave birth to her second child Maverick Jax last spring, and the six-month-old baby boy is her first child with husband Matt Ericson. She also is a mom to daughter Leiana, whom she shares with her ex-husband Leif Manson.

She was extremely open about the complications in her second pregnancy, which was documented during the last season of the hit Lifetime reality series. Since her pregnancy was high-risk, little Maverick was born one month premature and he had to remain in NICU care because his lungs were underdeveloped.

But now Briana and baby are doing just fine, and the doting mommy constantly updates fans on her son’s progress via social media. She shared photos from her son’s first Christmas and Thanksgiving, and she even posted a side-by-side of her baby boy at six months with her hubby Matt at six months — and little Mavi looks just like his daddy!

The adorable little boy even hit a developmental milestone recently. In a video posted to his very own Instagram account — run by Briana and Matt — Maverick cooed as he gnawed on a blanket.

“It's teething time & I'm happy as long as I have my blanks,” the caption read.
