Why You Should Never Mess With Rihanna

What Was Said: Earlier this week, TLC's T-Boz and Chilli slammed Rihanna during an interview on an Australian TV show, saying that she shows too much skin. T-Boz explained: "Every time I see you, you don't have to be naked. We became the biggest selling girl group with our clothes on, and that says a lot. It's easy to sell sex. We could go around with boobie cakes all day long."

How Ri Responded: Rihanna shot back at the girl group by posting a picture of herself with her tongue out on Twitter and writing, "When there's no changing that fact that I'm me, and they're well . . . they're them." She also changed her Twitter header photo to a throwback shot of T-Boz and Chilli posing topless.

What Was Said: In May, Charlie Sheen kicked things off by posting one of his infamous "Twitter poems" about an alleged negative encounter he had with the singer. Apparently, Charlie had asked Rihanna to meet him and his fiancée, who was celebrating her birthday. When Rihanna's team said that the meeting wouldn't be possible because of photographers, Charlie was not pleased. He wrote: "Sorry we're not KOOL enough to warrant a blessing from the Princess (or in this case, the village idiot)." Charlie added, "Here's a tip from a real vet of this terrain; If ya don't wanna get bothered, DON'T LEAVE YOUR HOUSE!"

How Ri Responded: While never naming Charlie outright, Rihanna referenced the actor's rant on Twitter, writing, "If that old queen don't get ha diapers out of a bunch." She also changed her Twitter header photo to a Photoshop of herself signing autographs for Charlie. The actor later responded by saying that "clearly English is NOT your primary language" and called her a "doosh."

What Was Said: Rihanna kicked things off this time around when she and her hairstylist spoofed a video that Teyana had posted of herself singing back in September. Teyana was not pleased, and sent out a barrage of since-deleted tweets to the pop star, writing, "F*ck all this industry sh*t, YOU and I know each other VERY well. Throwing subs 4 wat? You got my #, don't show off." After getting hit back by Rihanna's fan navy, Teyana continued, "Y'all could bully everybody else and get away wit that sh*t but that sh* ain't one work ova here. So y'all could miss me with that NAVY sh*t."

How Ri Responded: The "Diamonds" singer shot back at Teyana, writing on Twitter, "You will NOT get an @ from me! Not till you pay me! #nomorefreepromo #irefuse." More scandalously, Rihanna changed her Twitter background to a screenshot of Teyana's estimated net worth ($500,000) and hers ($90 million). She also tweeted a veiled reference to Teyana, writing, "I hate broke b*tches."

What Was Said: In June 2013, Liz Jones, a journalist for the Daily Mail, wrote a scathing op-ed on Rihanna, calling her "pop's poisonous princess," saying that she was a poor influence for promoting "drug-taking and drinking," and claiming that her revealing sense of style "invites rape." She also slammed the singer for having gun tattoos, false nails, and fake hair.

How Ri Responded: Rihanna shot back at Liz directly, posting an unflattering photo of the writer on Instagram and writing, "My money got a bad habit of pissing people off! If you sincerely wanna help little girls more than their own parents do, here’s a toxic tip: don’t be amateur with your articles, you sound bitter!" Rihanna also added that she has got her own "f*ck*d up sh*t to work on" and that she never portrays herself as "perfect."

What Was Said: During one of her low points in May 2013, Amanda Bynes tweeted to Rihanna, saying, "Chris Brown beat you because you're no pretty enough," and "I almost named my new dog Rihanna."

How Ri Responded: The Barbadian singer didn't reference Amanda directly but tweeted, "Ya see what happens when they cancel Intervention?" Amanda responded with more insults, writing, "Unlike your fugly faced-self I don't do drugs! U need the intervention dog! I met ur ugly face in person! U aren't pretty and u know it!"

What Was Said: When Ciara appeared on Fashion Police in February 2011, she trashed Rihanna for being rude, saying, "I ran into Rihanna recently at a party. She wasn't the nicest. It's crazy because I've always loved and respected what she's done in fashion. It wasn't the most pleasant run-in."

How Ri Responded: Rihanna was not happy that Ciara had trashed her on national TV and tweeted, "My bad Ci, did I forget 2 tip u? #howrudeofme." After some more social media back and forth, Rihanna decided to call a truce, tweeting, "Ciara baby, I love u girl! U hurt my feelings real bad on TV! I'm heartbroken! That's y I retaliated this way! So sorry! #letsmakeup." However, the truce did not last long as Ciara said in April 2013 that she doesn't know what Rihanna's problem is and called her "nuts." Ciara's fiancé, Future, also hinted that Ciara's public beef with Rihanna may have hurt his career as he never got to release his collaboration with Rihanna, "Loveeeeeee Song."

What Was Said: Back in March 2012, Chris Brown's on-again, off-again girlfriend, Karrueche Tran, took a jab at Rihanna on Facebook, writing, "I'm Angelina, you're Jen. C'mon you see where Brad is at." This was supposedly in response to an alleged jab from Rihanna after she uploaded an Instagram photo of a pack of rice cakes and wrote, "Ima make u my b*tch." (Karrueche is half-Vietnamese, so the rice cakes allegedly referenced her ethnicity.)

How Ri Responded: Rihanna shot back by taking a jab at Karrueche's self-proclaimed modeling career, writing, "I'm a leader y'all on some following' sh*t . . . coming in dis game on some modeling sh*t!"
