The Read All About It hitmaker, who has a number of inkings, is adamant the former Girls Aloud singer is "gorgeous" but he fears she is ruining her beauty with bad body art.
Last year (13), Cole unveiled an enormous bright red tattoo of roses covering her lower back and her entire buttocks, insisting she wanted a new inking after surviving a brush with death when she contracted malaria in 2010.
However, rapper Green, real name Stephen Manderson, fears his fellow Brit is destroying her natural beauty.
He tells British magazine Heat, "Cheryl Cole has got dreadful tattoos. (Her buttock tattoo) is done by one of my favourite tattoo artists. I just think she's got some horrendous tattoos; she's made some bad choices. She's gorgeous isn't she? She seems lovely as well, but yeah, bad tattoos!"
