The feud began at the Harpers Bazaar's Icons Party during New York Fashion Week earlier this year and has only gotten worse over time.
Most recently, Nicki claimed that is was Rah Ali who had beat Cardi up that night, and that she'd give $1000,000 to anyone who could get her footage of it.
Cardi wasn't happy with these claims, taking to Instagram to go on a HUGE rant about it.
In the videos, she claims that she was asked to collaborate with Little Mix on their new song "Woman Like Me" before Nicki was ever considered.
"Stop trying to distract everyone about the fact that you lied about Rah beating your head in," Nicki retaliated. "Babe we all get deals and turn them down. Same with songs dummy. Little Mix has been trying to get me on a song for 7 years. I finally found one I loved. Yes I passed on G-Eazy. What’s your point? Have you ever written a rap?"
But, it didn't take long for the Little Mix girls to chime in and claim that it was ALWAYS Nicki they wanted to work with.
"Sorry Cardi hun but this is the T. We’ve always wanted the Queen (no shade)," the girls wrote, sharing receipts.
Later on, the girls added that Cardi was also approached for the track, but they chose Nicki.
