Iggy Azalea a girl with a big booty

Amethyst Amelia Kelly (born 7 June 1990), better known by her stage name Iggy Azalea, is an Australian recording artist andmodel from Mullumbimby, New South Wales. She left for the United States at the age of 16 to pursue a career in hip hop music, first residing in Miami, Florida, and then other parts of thesouthern United States, including Houston, Texas and Atlanta, Georgia. She first gained recognition after the music videos for her controversial songs "Pu$$y" and "Two Times", went viral on YouTube. 

In September 2011, she released her debut mixtape Ignorant Art and subsequently aligned herself with Atlanta-based rapper T.I.. In March 2012, T.I. announced Azalea's signing to his record label imprintGrand Hustle. In July 2012, she released an EP executive-produced by T.I., titled Glory. After being signed by Wilhelmina Models, she began work modeling and was announced as the "New Face of Levi Jeans". 
Also in 2012, Azalea became both the first female and the first non-American rapper to be featured on XXL's annual Top 10 Freshmen cover issue.After label conflicts, her debut studio album The New Classic was finally released on 21 April 2014, under Virgin EMI and Def Jam Recordings. The album debuted among the top five of several charts worldwide and received generally mixed reviews. The album was preceded by four singles, "Work", "Bounce", "Change Your Life" (featuring T.I.) and "Fancy" (featuring Charli XCX). "Fancy" went on to reach number one on the U.S. Billboard Hot 100chart, with Azalea becoming only the fourth solo female rapper ever to top the Hot 100. Additionally, with Azalea featured on Ariana Grande's single "Problem", which rose to number two on the Hot 100, the same week "Fancy" topped the chart, Azalea joined The Beatles as the only acts to rank at numbers one and two simultaneously with their first two Hot 100 hits.^[2]Additionally, Azalea went on to pass Lil' Kim as the female rapper with the longest-leading number one single on the Billboard Hot 100 and moved into a tie for fifth place among lead women who have scored the longest commands on the Hot 100 this decade.

"Booty" is a song recorded by American singerJennifer Lopez for her eighth studio album,A.K.A. (2014). It was written and produced byCory Rooney, Lopez and Benny Medina, with additional writing from Chris Brown, Asia Bryant,Armando Pérez, Diplo, Lewis D. Gittus, Tedra Renee Wilson, and Danny Omerhodic. "Booty" samples "Dat a Freak", a song by Diplo & Swick, and it features Lopez's frequent collaboratorPitbull. Initially entitled "Big Booty", the song was first rejected by Lopez who disliked the idea of having a song titled "Big Booty". However, after playing the demo for her kids, they enjoyed the track and Lopez was convinced to record it, changing its title for "Booty". It was first premiered in a listening party she threw for critics in 2014. Initially, the album's version was announced as a single, with its coverart being released on August 13, 2014, however the remix version was released instead.

"Booty" is a dance track, with middle easternvibe, heavy percussion and Oriental keyboard riff, while its lyrics portrait Lopez inviting girls to the dancefloor to have a good time and dance, while shaking their butts. The song received generally favorable reviews from music critics, with many complimenting the song's fun nature, the dance environment and Pitbull's appearance, but a few dismissed its concept. Commercially, "Booty" performed moderately worldwide; it became a top twenty hit in the United States, charting at number eighteen on the US Billboard Hot 100, and entered the top forty in Canada, Australia and New Zealand, among other music markets.

"Booty" was teased during some concerts Lopez made in early 2014, being premiered fully at the free concert that Lopez made in the Bronx in June 2014, and later during the TV showGood Morning America and at the Fashion Rocks event. A one-minute teaser clip for the track was released on June 13, 2014, and it features Lopez and a group of women twerking. The teaser-video received high prase for its visuals and choreography, while Lopez was complimented by critics for looking rejuvenated and younger. 

But  the world of music it also has disses 

Nicki Minaj Disses Iggy Azalea at BET Awards.

At last night's BET Awards, Nicki Minaj was presented with the award for Best Female Hip-Hop Artist. During her acceptance speech, she appeared to poke at Iggy Azalea, who was also nominated in the category. "What I want the world to know about Nicki Minaj is when you hear Nicki Minaj spit, Nicki Minaj wrote it," she said, before striking a number of exaggerated poses. During the ensuing applause, she kept saying "No shade" (implying: yes, shade) before finishing her speech. Watch a video below, via Consequence of Sound.

Some context: Azalea's been dogged by rumors that she uses a ghostwriter, though no conclusive evidence has emerged. Minaj's pointed insistence that she writes all her own raps, then, would be a little fun at Azalea's expense. Recently, Minaj also took issue with a Forbeswriter's assertion that Azalea was running hip-hop.

Looking for more evidence? Well, there was the way she danced during Azalea's performance of "Fancy" during the show. You can watch a Vine of that below, also via Consequence of Sound. Sarcastic dancing: 2014's new battleground!

But all this things i think they are bullshits cause they are both amazing and gorgeous 
and if they work together they can creat a magical melody ....
