Brielle Biermann has had enough of people thinking she doesn't have a job. The "Don't Be Tardy" star set the record straight about how she makes her money when she responded to a Twitter fan on Sunday.

"WHY do people think i don’t work? Why?" Brielle asked. "Bc i don’t go to a 9-5? I have been on reality tv since i was 10 (job number 1!) i have a makeup line and partnerships with SO. MANY. COMPANIES. That i truly love. So? Lol"

The tweet was the 22-year-old's attempt to defend herself from a fan who accused her of spending "mommy's money."

"Living off of mommy’s money," the Twitter user wrote in response to Brielle questioning a purchase she made while under the influence.

"I really need to stop booking flights when I’m drunk but isn’t this just me living my best life?" she tweeted.

Defensive outburst aside, Brielle does, in fact, seem to be living her best life perhaps even with a little bit of company. Back in July, she was photographed with a new mystery man, who was later identified as UCLA baseball player Justin Hopper by OK magazine, as she attended the wedding of YouTubers Tana Mongeau and Jake Paul in Las Vegas.
