And Brielle Biermann got real with her 1.3million followers on Tuesday by uploading an unedited picture of her pert backside to Instagram.

Brielle had on only a matching sports bra and thong panty set that came in a pretty shade of pink.

She added that achieving a picture of one’s derriere, such as hers, is ‘all about the angles.’

In the photo, Biermann rocked a noticeable full-body tan and her length brunette hair flowed down her back in loose waves.

The reality star also appeared to be wearing little to no makeup at the time the self-portrait was taken.

Brielle snapped the post-polls selfie inside of her luxury vehicle before heading back to her mother Kim’s lavish Atlanta home.

Although fans have to wait until November 10 to catch a new one, last week’s episode of Don’t Be Tardy came through with the drama.

During the episode, the family’s trip across the United States came to a halt after Zolciak’s RV’s engine failed.

It happened in the middle of nowhere as the gang was hurtling toward Amarillo, Texas, to visit a dude ranch.

Kim’s husband Kroy Biermann, 35, insisted that he knew what was going on when red lights started flashing in the vehicle and the sound of small electrical pops were heard. 

But Kim, a 42-year-old ‘helicopter parent’ who constantly worried about her six kids, wasn’t so sure.

Tony Biancosino, the show’s executive producer, reassured the family he was in a vehicle behind them, as someone theorized it might be the engine.

‘I’m really f***ing stressed out,’ Kim said in a confessional. ‘I’m like, in a bad dream.’ 

After a ton of drama regarding the RV’s prognosis, the teaser for the series’ November 10 episode revealed that Kroy discovered that there was a short in the engine.
