It seems Rihanna has finally had enough of Chris Brown ... the singer has "unfollowed" her ex-boyfriend on Twitter after he released a new diss track that appears to be aimed at her.
The song in question is a remix of Kanye's TheraFlu -- in which Brown freestyles the verse, "Don't f*ck with my old bitches ... like a bad fur ... every industry n*gga done had her."
He continues, "Trick or treat like a pumpkin ... just to smash her."
Hours after Brown released the track last night, Rihanna stopped following Brown on Twitter -- a HUGE move -- and one that's leading many to assume Rihanna believes the verse is about her.
A short time later, Brown unfollowed Rihanna.
We reached out to Rihanna's rep -- so far, no comment.
Rihanna is adamant ... she's NOT dating Raiders running back Darren McFadden -- despite reports the two were spotted making out in Hawaii a couple weeks ago.
Sources close to Rihanna tell us, the singer did meet Darren last month in Honolulu -- while she was promoting her new film "Battleship" -- but they kept things strictly platonic.
We're told Darren -- who was WITH HIS GIRLFRIEND -- introduced himself to Rihanna as a fan ... and Rihanna bought Darren and his GF drinks on the beach. That's it.
But that doesn't mean Rihanna can't support her new pal -- which might explain why the singer wore a Raiders jersey to a New York strip club last week.
There's a reason Rihanna's arm was hooked up to a bunch of needles and tubes yesterday -- sources close to Rihanna tell TMZ, the singer had been struck down with a bad case of the flu ... and required an IV drip.
Sources tell us, she started feeling really ill last week and saw a doctor on Thursday ... but by the time of her "Saturday Night Live" appearance, she still wasn't fully recovered.
As we first reported, Rihanna missed the SNL dress rehearsal because she was sick -- but show producers didn't buy her excuse ... insisting she didn't appear ill.
But looks might be deceiving -- because we're told Rihanna wasn't just ill during her SNL performance, she also continued to feel sick the next few days ... and her doc was forced to put her on Penicillin.
Soon after, Rihanna began to experience flu-like symptoms -- requiring IV treatment yesterday, which is when she posted the above picture on Twitter.
Rihanna was a no-show for her final rehearsal for "Saturday Night Live" last night -- which did not sit well with the show's producers, including head man Lorne Michaels ... TMZ has learned.
According to our sources, RiRi called in sick for the dress rehearsal, which is done live in front of a studio audience right before the actual show. We're told Michaels takes dress rehearsals very seriously and was quite upset when Rihanna bailed at the last minute.
Our sources say that in her place, Rihanna's choreographer danced to her songs.
When Rihanna showed up later looking just fine, we're told the staff was shocked ... and felt she didn't appear sick enough to have missed the dress rehearsal ... though no one from the show called her on it.
According to our sources, once the live show got going, Rihanna was seen eating an apple and walking around in between songs ... which bothered several staffers because she did not seem ill at all.
We're told producers can't even remember the last time someone has skipped the dress rehearsal.
Sources close to Rihanna tell TMZ she went through every rehearsal except the dress rehearsal (which she was in the building for) because she just felt too ill to do it. We're told RiRi had a doctor come to her dressing room before the show and administer a shot of penicillin before she went on.
A rep for the singer tells TMZ, "Rihanna was sick and needed to save her voice for the live show."
Rihanna loves drinking beers and making it rain at strip clubs so much -- it's almost like she's actually a dude ... but she's totally NOT. Right? RIGHT??

Rihanna's up to her usual thigh jinks again -- showing off her tight gams during a quick trip to Hawaii Friday ... and single-handedly raising the temperature of the Pacific Ocean in the process.
With reports Rihanna wants to play Whitney Houston should there ever be a biopic about the legendary singer -- Whitney's daughter, Bobbi Kristina, is telling friends there is only one person that can play that role ... HER.
According to our sources, Bobbi feels she is the perfect person to play the part of Whitney ... telling friends that no one knew her better.
Our sources say BK feels that if Easy E's son can play him in a movie, she can do it too.
So if such a project ever develops, the producers can expect a call from Bobbi Kristina.
There's only one way to ask Rihanna if she's hooking up with Ashton Kutcher -- and this is not it. Thanks, British reporter ... for failing so miserably it was comical.

Screw the brutal, face-smashing beating in 2009 ... Chris Brown is the HOTTEST R&B artist out right now -- which is why Rihanna says she reached out to CB to collaborate on two new songs.
Rihanna called Ryan Seacrest this morning on KIIS FM, explaining her choice to record two duets with the man who brutalized her three years ago -- "I reached out to him about doing ‘Birthday Cake’ because that’s the only person that really -- it made sense to do the record. Just as a musician -- despite everything else -- that was going to be the person."
She said, "I thought about rappers, and I’ve done that so many times, and the hottest R&B artist out right now is Chris Brown. So I wanted him on the track."
Rihanna doesn't think she's to blame for the see-thru pics of her upper lady parts this week -- despite the fact she wore a mesh shirt with no bra -- insisting it was camera flashes that left her exposed.
The singer was out in NY last night ... happily taking pictures with EVERY fan who wanted a shot ... when someone asked if she had seen the racy see-thru pics. She replied, "You mean my t*tties?"
This time, all RiRi exposed was a smile ... as she joked, "You come up with the flash man!"
Actually, YOU came up with the flash, man ... but no complaints here.
Before Justin Bieber went toe-to-toe with a photographer -- sparking a police investigation -- he trained with "Iron" Mike Tyson! Wondering how they ended up together? Well, we got Tyson on the phone ... and you won't believe his excuse for kicking it with Biebs. Plus,…
