The singer's latest Instagram snap showed off her newest ink addition, a tribal arrow design in white ink alongside her index finger - just weeks after Cara revealed her lion design also on her index finger.
And it seems hand tattoos are emerging as a major trend right now. While Ellie already boasts one hand tattoo - a simple triangle design on her inner wrist to join the arrow etching - Cara added her initials, calligraphy style, along the side of her hand to keep the lion company.
The pair look like they're becoming close friends, along with Cara's "wifey", Rita Ora. And with Cara and Rita front-runners in the new-wave in-crowd - their attendance at the Fran Cutler party alongside party veterans Kate Moss and Sadie Frost firmly cemented their place on the It-girl party circuit.
What will the girls get up to next..?
