AceShowbiz - It's time for sisters to hang out! Brielle and Ariana Biermann were spotted hitting the town with fellow sister duo Scarlet and Sistine Stallone. The daughters of Kim Zolciak looked like twins during the fun outing on Thursday, August 8 in Los Angeles with their similar blonde locks.

The sisters were photographed entering Craig's in West Hollywood. For the night out, Brielle Biermann opted for a denim T-shirt dress. Meanwhile, Ariana was looking casual in a cropped white bralette and ripped jeans. As they sported similar makeup and mermaid-length blonde waves, the "Don't Be Tardy..." stars looked as if they were twins.

Meanwhile, Sylvester Stallone's daughters arrived in coordinated outfits. Scarlet Stallone and her sister Sistine looked stunning in black tops. They both paired the look with jeans and black lace-up boots.

The Biermann girls and the Stallone sisters had been hanging out a lot lately. Prior to this, Kim's eldest daughter posted a video of them enjoying delectable grubs like hamburger and steak and wrote in the caption, "When you come to LA solely to have dinner with your favs." Joining them was pal Austin Anderson.

Back on July 20, the sisters were also see reuniting over food at Delilah where they had chicken nuggets. It was before the Biermann family was kicked out from their flight to Atlanta because of a holdup over Kroy Biermann's service dog.

Kim detailed the ordeal on her "House of Kim" podcast, claiming that Kaia's twin brother Kane was left behind alone by gate agents from Delta as they removed his siblings off the flight while she was in the bathroom with Kaia. "I didn't know what was going on," the 41-year-old Bravo star said.

"Who the f**k touches my children, removes my bag, and removes my kids from a plane without a parent? Are you out of your f***ing mind? … It's a criminal thing when you're taking kids off a plane and people's bag," she continued, adding that she had gotten police involved in the drama.
