The 27-year-old posted a photo on Instagram of himself brandishing his middle finger, while posting the apparent song lyrics: "Tell a hater I say.... F**k you, F**k you, F**k you."
After posting the image of himself in a nightclub, some users accused Nasri of failing to stick to his religious beliefs, which include Muslims fasting during the holy month of Ramadan.
According to the Daily Mail, Nasri's Brighton-born girlfriend took to Twitter to write: "Yes hes fasting! Even on his holiday!"
Reports have claimed that the image was taken during a holiday in Las Vegas earlier this summer, prior to Ramadan.
