The 20-year-old model will be accompanied by her New York based tattoo artist friend, Bang Bang, so as her A-list buddies can have the best inking experiences, reported Contactmusic.
"Cara couldn't decide between a muddy UK field and guaranteed sunshine for the celebration so she decided to make her own festival in Ibiza. Rita Ora and Rihanna will be encouraged on the microphone," a source said.
Stars like Pixie Geldof, Jade Jagger, Georgia Jagger and Kate Moss are expected to attend the private bash.
Delevingne is believed to have been drawn towards body art after Bang Bang inked her index finger with a lion.
