"Famous" features vocals from Barbadian singer Rihanna and ad-libs from American hip hop artist Swizz Beatz, and enlists samples of Jamaican singer Sister Nancy's song "Bam Bam" and "Do What You Gotta Do" by American singer Nina Simone. The single was serviced to US urban and rhythmic contemporary radio stations on March 28, 2016, and was confirmed for release three days before.^[2] It was sent to Italian contemporary hit radio stations on April 15 by Universal. Upon its release, "Famous" was met with both critical acclaim and scrutiny for a controversial lyrical reference to American singer-songwriter Taylor Swift, partially in relation to West's interruption of her 2009 VMA acceptance speech. After West claimed to have obtained Swift's approval over the criticized lyric, Swift denied the claim, criticizing West and denouncing the lyric as "misogynistic" in a statement. Several months later, West's then-wife Kim Kardashian released a three-minute video capturing parts of a conversation between Swift and West in which Swift appears to approve a portion of the lyric.^[3][4] In 2020, a 25-minute uncut version of the video surfaced, establishing that West did not appear to tell Swift about the specific line ("I made that bitch famous") which she had objected to - Wikipedia.
