Nicki Minaj spoofed Kim Kardashian during her appearance on "Saturday Night Live" out of fun, but a new report says Nicki personally has a grudge against Kim. For her, Kim is nothing but a "fake copycat."

OK Magazine reports that "Anaconda" singer Nicki Minaj told her friends that Kim Kardashian is a big "fake copycat" after seeing her nude photo for Paper magazine. The reality star wanted to "break the Internet," but all she came off to Nicki Minaj as an imitator of her famous "Anaconda" album cover. Nicki also dissed Kim's butt behind her back, doubting if the butt is real or not. The thing is, she's not going to go public and ask that since her "Anaconda" cover got some people asking if her butt is also real in the photos. "She also agrees with the rest of the world that Kim's butt is not natural, although she'd never come out and say that publicly -- she knows she's got question marks over her own derriere," the source said.

Nicki however, now thinks Kim Kardashian is too late on the "booty game," as it is already passé. "Nicki's already over that whole booty thing and exploring new ideas," the insider shares to OK magazine.

Probably to have fun subtly at the expense of Kim instead, Nicki Minaj just impersonated the "Keeping Up with the Kardashians" star on SNL's "Weekend Update," saying her (Kardashian's) Paper magazine photos were actually a "Public Service Announcement" about the importance of getting regular gynecologist checkups, academic exercises and a Jewish greeting card. She also impersonated Beyoncé that night flawlessly.

Twitter users were all praises for the rapper. Most of them said the rapper made the show more interesting to watch. Many also said she nailed "Kim Kardashian" and it is one of the "best SNL" skits in awhile. Many could not get over how hilarious she was on the show and said she should even be a host of SNL.

She also partnered with guest host James Franco to share their views on Peter Pan Live, which is a TV event which screened in the U.S. last week and performed two of her hits.
