She also claimed she'd spent 10k fixing his baldness, even claiming Tyga had gotten the same procedure, the Daily Mail reports.
Samuels meanwhile claimed the Queen star was only acting the way she was on social media because her album had just dropped.
The bout seemed to kick off when Nicki exploded when old rumors her ex had previously written some of her lyrics for her resurfaced — something she always furiously denies.
During an interview on Hot 97, Funkmaster Flex lit the fuse — and instantly regretted it — by mentioning the her ex's name.
Nicki angrily slammed Samulels for lying and then later backtracking when the potential damage had been done.
"You lie about someones craft, and just because they're a woman they will believe you?" she spat, reaffirming her mantra she has held throughout her career: "No man will ever write for me."
She accused him of "biting the hand that feeds", and claimed his family said she was "a lazy b****" for pursuing her rap career — when it was she who was supporting him with what little money she had before her success.
Her fury quickly boiled over onto Twitter when Safaree heard his name mentioned, and noted how Nicki still bristled.
"Unless I really cared still I could not let the mention of someone's name get me that riled up. That looks like some1 who either stlll cares or just holding on to a lot of hate towards someone," he tweeted. "How many times have I said I never wrote ur raps? Nobody even talks about that anymore."
He denied some of Nicki's accusations — including that he'd stolen her credit card and used it to pay for prostitutes — claiming he was the one to call time on their relationship because it had turned "toxic".
He also accused her of "messing" with Meek Mill years before they split.
"You hold on to everything," he said. "And now I stole your card? The 1 you gave me the pin for...?"
"Towards the end it got toxic and I just packed up and left. I did things for spite and so did you. I don't wish you bad and I don't want us back together just like I'm sure you don't. I don't need you you don't need me but we will always be linked in the public no matter what.
"We know each other inside out. Everything there was for us. I didn't use your card for prostitutes. We both didn't trust each other. You did sh*t I did sh*t. You said you were messing with meek a few years b4 y'all got together and I'm not mad at that."
It was then he claimed Nicki had almost killed him with a knife: "Remember the night you cut me and i almost died the police and ambulance had to take me out the crib on a stretcher and I had to lie and tell them I was trying to kill myself so they wouldn't take you to jail. When things like that start happening more Than once it's time to dip."
But Nicki didn't take any of his tweets lying down.
"Sherika & I had a bet that soon as you knew meek was bout to come home your crawl back & ya did! came to my house CRYING. JOYCE WAS THERE! My whole glam was there! Left who?!?! You gettin aired out on #QueenRadio too on Thursday! Apologize & STFU"
Then Nicki got personal, claiming she'd paid to fix his baldness— and even dragged Tyga's hairline into it.
"I should've never paid for that gyatDamn hairline!!!! It fell back out cuz God don't like ugly!!!! You used me but God had other plans!!!!!" she spat.
"Tyga sh** ain't fall back out!!!! Y'all went to the same doctor!!! Yours fell out cuz GOD DONT LIKE UGLY!!!!!!"
Fellow rapper Charlamagne Tha God then hilariously got involved, asking Safaree for a referral.
"I know you see me text your phone bruh. Answer my damn question!!! How much for the hairline??? Stop holding out on the bald bros!!! @iamsafaree"
Nicki even responded with a price: "10 racks".
Safaree took the bait, and continued discussing Tyga's cosmetic treatments.
"1st off Me and tyga didn't go to the same dr. We did it the same day. Diff doctors . Listen I don't know if this has to do with 1st week sales but you need to finish your zen. And don't talk about vh1 checks cuz the way you're acting it's like your auditioning to be on LHH" (Love & Hip Hop).
Nicki wasn't finished airing dirty laundry however, referencing an incident in which her ex sent an ill advised explicit photo.
"Btch you hit me & meek asking us to get your dick pic back from someone. Lol. You were playing with ur d*ck in the shower by urself with suds & sh*t. I have the email where u said you couldn't pay ur electric bill & why you lied on me but go AWWFFF SIS!"
Waving the white flag, Safaree backed off insisting he wanted an amnesty, but fired parting shots accusing the Chun Li hitmaker of merely trying to drum up publicity for her new album.
"At least y'all know I was trying to keep my nudes to myself now. Some1 was trying to leak my di%^ pic for years and ive been trying to stop it forever," he admitted. "But is this suppose to be your promo run? I'm flattered that you feel talking about me can help. I can't believe ur still mad.
"And you know what I still don't have no hate for you cuz I'm happy in my own mind now. Enjoy your album dropping. And stop letting these ppl see you sweat. This ain't you. You too big to act the way you be acting. No1 on ur level acts like that. Period
"It's about to be 5wholeee years. There's no way I could hold on to something that long. You can front all you want you're not happy."
