Nicki Minaj has been very busy on Twitter within the past week. First, she slammed fellow 'American Idol' judge Mariah Carey for being "insecure" and "bitter," and now she's taken 'Access Hollywood' to task for a scathing article a reporter wrote about her.

In an open letter, 'Access' correspondent Laura Saltman wrote about her displeasure with the Queen Barbz's alleged backstage behavior on 'American Idol.'

An excerpt from Saltman’s article reads:

In my 20 years in entertainment news, I have interviewed close to 5,000 celebrities -- people who have bigger bragging rights than Nicki. Men and women who have Oscars, Grammys and Emmys. Yet, by far, she is the most ungracious of anyone I have met.

Each week, she comes backstage for interviews and we are told “two questions only” while her people hover over you and even, at times, have their hand on your arm as you end your interview to make you stop. Waiver from the two-question rule and Nicki herself will walk away. She makes zero eye contact and has no connection to whomever is interviewing her. If she likes your question, she may give you a proper answer. If she doesn’t, she may give you a dirty look and walk off. After she posted mean comments about Mariah on Twitter yesterday calling her “bitter” and “insecure,” I wanted to give her the opportunity to redeem herself or perhaps apologize. I phrased my question that her comments had caused quite a stir online and asked if she had anything to say about it. She looked at me and told me my question made no sense and when I tried to explain it further she just said “goodnight” and walked off in a huff."

Saltman further adds that Minaj's cyber-bullying against Carey is not needed in the realm of reality television.

"The truth is that 20 years from now, Mariah Carey will still be known as one of the best female vocalists of all time. Nicki Minaj – well, I will let you decide that," she writes.

Ouch!

Of course, Minaj wasn't going to let those comments slide. The 'Freedom' rapper went on Twitter and went h.a.m. on Saltman and fellow 'Access Hollywood' host Billy Bush.

"Honestly, if your day was really RUINED because i walked away from a question, rather than discuss something negative, u need a LIFE. Lmao," she tweeted. Yo @LilTunechi This h-- want some trukfit."

She then added: "The audacity of you to call me nạsty with your one sided journalism. Thats what u ppl do. Yes. I AM the female Kanye cunt @billybush."

"Barbz, this is why I stress the importance of hard work, ambition & higher education. These ppl want so bad to keep us down," she continued.

Finally, Minaj wrapped it up by throwing more shots at Saltman and Bush.

"See, nothing scares me....don't need any show, any audience, any endorsement...God is real. I'm just enjoying life...whr he brought me from," she wrote. "Ay yo @RyanSeacrest, looks like I found your stunt double...I call dis young Diva Lyin Seacrest… @billybush."

Saltman responded on Twitter, writing, "Never been called a h– before by a pop star! Badge of honor! U go!” Billy Bush also chimed in tweeting, "Come see me on @liveaccess @nickiminaj lets talk about that huge chip on your shoulder."

No word if Minaj will accept Bush's offer to chat, but it's a sure bet that she won't be doing backstage interviews with 'Access Hollywood' anytime soon.

Can't we all just get along?
