Brielle, 22, and Ariana, 17, partied with Scarlet and Sistine Stallone.
They were seen arriving at celeb hotspot Delilah in West Hollywood.
Ariana sported a strapless top that showed off her midsection during their LA outing.
She also wore a pair of lime green pants and orange belt that came off looking more loud than fashionable.
Brielle revealed on her Instagram story that the party of four ordered $100 dollars worth of chicken nuggets while at Delilah.
The sisters have partied at LA hotspots over the past week including Catch and many more.
