Earlier this week, we already got the tea from her NY Mag interview that Cardi B stays making money moves.

She allegedly garnishes $20K a month for her legendary Fashion Nova posts and around $50,000 per gig these days. Yeah, our girl is looking like money but don't ever try to "finesse" her — unless you want to get called out!

Which is exactly happened when a hairstylist charged Cardi $400 to flat iron her lace front wig. Not one to hold her tongue, Cardi took to her her 12.9 millions Instagram followers to vent:

She even posted a photo with the caption, "Mind you my hair was styled since yesterday. How you gone charge me 400 dollars to flat iron my hair and you come for 30 minutes? Naaaa A, dont care how much money I'm making f**k outta here."

Yikes, we aren't sure exactly who she's calling out but we doubt they'll work together any time soon. Do you think it's fair that celebrities are overcharged for basic services or should they pay up without complaining?
