Rappers Snoop Dogg and Iggy Azalea appeared to be at odds after Snoop posted a photo of a man on Instagram with the caption: Iggy Azalea No Makeup." The Australian rapper fired back with series of tweets that she later deleted. Snoop then posted a screen grab featuring a story headline of their supposed feud that claimed Azalea was "fuming mad." She later took to Twitter to say she wasn't "fuming mad" at anyone. For the record, we think Azalea looks just fine without makeup.

Kanye West and Jimmy Kimmel
A skit poking fun at Kanye West on ABC's "Jimmy Kimmel Live" provoked an irate call from the rapper and flurry of tweets rallying against Kimmel in fall 2013. The late-night TV host said he somehow found himself in a "rap feud." And despite speculation that it was all staged, during West's Oct. 9, 2013 visit to the show, both stars insisted it was not a publicity stunt. By the end of the segment, they appeared to make nice, with Kimmel saying he felt bad about the sketch.

Justin Bieber and Seth Rogen
Actor Seth Rogen is no fan of pop star Justin Bieber.
During an appearance on "The Howard Stern Show" on May 5, 2014, Rogen said that he had not been impressed by his past meetings with the Biebs, who seem "nonplussed" by their encounters.
"Seth Rogan [sic] sorry I didnt bow down when I asked 2 meet u was probably a bit shy," Bieber retorted in a Twitter post on May 8, 2014.

Sinead O'Connor and Miley Cyrus
Sinead O'Connor and Miley Cyrus got into a war of words after the Irish singer posted an open letter to Cyrus on Oct. 3, 2013, warning her not to "obscure your talent by allowing yourself to be pimped, whether it's the music business or yourself doing the pimping." The advice didn't go down well -- Cyrus responded on Twitter by mentioning O'Connor's struggles with bipolar disorder and comparing her to troubled star Amanda Bynes. O'Connor responded with another open letter the next day, in which she denounced Cyrus for mocking mental illness. Cyrus again replied via Twitter, writing, "If youd like to meet up and talk lemme know in your next letter. :)"

Sylvester Stallone and Bruce Willis
Tension started to grow in August 2013 between Sylvester Stallone and Bruce Willis after Stallone tweeted that Willis wouldn't be appearing in "Expendables 3" and that Harrison Ford has been tapped to join the film instead. But he took it a step further with the follow-up tweet, which called Willis "greedy" and "lazy." Sounds like bad action-star brawl just waiting to happen.

Madonna and Elton John
The Material Girl and the Rocket Man, once friends, have had a long-standing feud going back at least 10 years and involving competition for music prizes, charges of lip-synching, spurned party invitations and returned Christmas cards, among other things.
As recently as August of 2012, Elton John said Madonna's "career is over" and called the 53-year-old singer a "fairground stripper."
Mariah Carey and Nicki Minaj
Reports of a feud starting brewing between Mariah Carey and Nicki Minaj as soon as they were announced as judges on "American Idol" in September 2012. At the time, Carey said it was too soon for a fight, but a couple of weeks later a video surfaced that proved otherwise.
The blurry web clip, released by TMZ, displayed what appeared to be an argument between Minaj and Carey during an audition taping in Charlotte, N.C. A couple of days later, Barbara Walters said Mariah Carey told her that she beefed up security after Minaj threatened to shoot her.

Madonna & Lady Gaga
Madonna and Lady Gaga were once friends and collaborators (the pair appeared in a sketch on "Saturday Night Live") but things got weird when Gaga released the song "Born This Way" in 2011.

Paris & Zeta
Diamond heiress Zeta Graff claimed that Paris Hilton planted an unflattering item in the New York Post in 2005. According to the story, Graff went "berserk" in a London nightclub and tried to strangle Hilton and steal her diamond necklace. Graff sued Hilton for $10 million, but the two settled before it went to trial. Graff dated Paris Latsis before he was engaged to Hilton.
Paris & Lindsay
Although they, too, appear to be friends again, the Hilton-Lohan feud has many facets. In May, Hilton friend Brandon Davis launched a verbal assault on Lohan. Hilton also previously confronted Lohan at a New York club because Lohan had gone on a few dates with her ex-boyfriend, Stavros Niarchos.
Paris & Nicole
Best friends since childhood, Paris Hilton and Nicole Richie have never revealed the exact cause of their falling out in 2005. But the stars of the reality series "The Simple Life," appear to be friends again and agreed to reunite in a fifth season of the show as camp counselors. However, production was riddled with complications, including the legal woes of both gals.
The Donald & Martha
The Donald has had his share of feuds -- with his ex-wives Ivana and Marla Maples and also with his friend, Martha Stewart. The two were all smiles in August 2005 when their were promoting their "Apprentice" shows. But Martha's version was a bust, and Trump blamed his sagging ratings on her show.
Tori, right, and her parents, Aaron and Candy Spelling, left, reportedly were on the outs after Tori left her first husband Charlie Shanian for married actor Dean Dermott. Tori later starred in a TV parody of her family's lavish lifestyle called "So NoTORIous." Tori reconciled with her TV mogul father just before his June 2006 death. The birth of Tori's son on March 13, 2007, apparently has helped mend fences with mom.

Rosie & The Donald
The fight between Donald Trump and Rosie O'Donnell first broke out in December 2006 after Trump announced that Miss USA, Tara Conner, would keep her title, which had been in jeopardy because of substance abuse.

Tyra & Naomi
A feud between supermodels Tyra Banks, left, and Naomi Campbell that went on for more than a decade reportedly stemmed from battles of being the No. 1 black supermodel in the industry. As you can see, the beauties, shown on March 2, 2007, have since made up.

Davis & Crawford
While some feuds go on for years and others are resolved, some people die hating each other. That was the case in the feud between actresses Bette Davis, left, and Joan Crawford. In the 1962 film "Whatever Happened to Baby Jane," they so-starred as aging Hollywood sisters with thoughts of revenge and jealousy against each other. Although the movie gave both real-life aging actresses a career boost, they hated each other.

B.I.G. & Tupac
It is debated that a feud between rappers Tupac Amaru Shakur, right, and Christopher "Notorious B.I.G." Wallace, over lyrics in a song written by Shakur, ultimately led to their deaths. Shakur, 25, was gunned down in a drive-by shooting in L.A. on Sept. 13, 1996, with speculation that Wallace was involved. Six months later, Wallace was killed in the same manner in Las Vegas.
