People.com Celebrity Bad Blood: 2014's Biggest Celebrity Feuds Gwyneth and Martha trade barbs over baked goods, Bette thinks Ariana's too sexy too soon, and more of the year's headline-making spats By Brooke Showell Published on December 5, 2014 05:00 PM Share Tweet Pin Email 01 of 05 ARIANA & BETTE Ian Gavan/Getty; Jennifer Graylock/INFphoto Those are fighting words! "You don't have to make a whore out of yourself to get ahead," Midler told the U.K.'s Telegraph in November, in reference to 21-year-old Grande's image. Grande aired her grievances in today's public forum of choice – Twitter – to proclaim that Midler had always been a feminist "who stood for women being able to do whatever the F they wanted without judgment! Not sure where that Bette went but I want that sexy mermaid back." Shell bra or cat ears, it's all good now. "About my screed on @ArianaGrande, all I can say is, 'Spoken like a reformed old whore!'" Midler responded as a mea culpa, but never without humor: "She does have a beautiful voice, on a couch or off." 02 of 05 GWYNETH & MARTHA John Angelillo/Landov; Theo Wargo/Getty The domestic diva showdown began in 2013, when Stewart spoke out about Goop founder Paltrow's homey ambitions. "I think I started this whole category of lifestyle," Stewart stated. The hits kept on coming this September, when Stewart told the actress (via Net-a-Porter's magazine) to "be quiet." Paltrow seemed energized by the insult: "I'm so psyched that she sees us as competition," she responded, and fired back by hiring a former Martha Stewart Living Omnimedia exec as Goop's new CEO. The sparring continued: Stewart's magazine poked fun in a feature on holiday pies titled "Conscious Coupling," while Goop responded with a jailbird cake. 03 of 05 JAY Z & SOLANGE CDNY/Broadimage; Scott Barbour/Getty Beyoncé said it best: "Of course sometimes s– goes down when there's a billion dollars on an elevator." While it's unclear what exactly went down on that fateful evening in May, everyone could see that Bey's sister Solange was obviously angry when she reportedly attacked her brother-in-law Jay Z in an elevator at a Met Gala after-party. The family has since kissed and made up, and Mr. and Mrs. Carter were on hand to celebrate Solange's November wedding. 04 of 05 JUSTIN & ORLANDO Ari Perilstein/Getty; Dave J Hogan/WireImage There's no risk of a bromance between Bieber and Bloom. All was not so sunny in Spain this summer, when the pop star and the actor allegedly got into an altercation at a restaurant in Ibiza in July. Sources guess this was a scuffle over their gorgeous girls: Bieber may have said something rude about Bloom's ex-wife Miranda Kerr, and Bloom had been spending time with Bieber's ex-girlfriend Selena Gomez. While there was no clear winner, it was Jimmy Fallon who had the last word: "Orlando Bloom apparently threw a punch at Justin Bieber last night during an argument at a nightclub. Orlando's hand was pretty sore today, you know, from all the high fives he got." 05 of 05 ADRIENNE & KIM Alberto E. Rodriguez/Getty (2); Scott Barbour Reality bit former Cheetah Girls star and The Real host Bailon, who said that televising her relationship with Rob Kardashian on Keeping Up with the Kardashians may have held her back professionally. "To be stuck with that Kardashian label, that was so hurtful to me and to my career," she told Latina in September, five years after the couple split. Leave it to Rob's Twitter-happy big sis Kim to jump to her brother's defense: "Funny how she says being with a Kardashian hurt her career yet the only reason she has this article is bc she is talking about a Kardashian," she posted. Oh snap!
