In response, Chrishell Stause posted a side-by-side image of herself and Cardi, explaining that they were both wearing dresses from the same designer, reports femalefirst.co.uk.
Chrishell, 41 - who is best known for starring in 'Selling Sunset', the hit Netflix show - wrote: "We wore the same designer @GG_Studio."
Meanwhile, Cardi previously said to being happier before she became famous.
The 'WAP' hitmaker - who married rap star Offset in 2017 - no longer worries about her financial situation, but Cardi insisted she felt happier "two or three years ago".
She said: "One positive thing is that, my family, whatever they want, they get. Everything that I want to buy, I can get. I don't have to worry so much about my future. One negative thing is that, even though I'm happy, I feel like I was a little bit happier two or three years ago when I had less money."
Cardi also felt she had a greater degree of control over her own life before she became a global star.
