Cara Delevingne got two new tattoos despite warnings from her modelling agency.

The 21-year-old model has received a flurry of backlash from fashion houses, Chanel and Burberry after she ignored stern advice from agents who say her growing collection of body art is putting her career at risk.

Cara braved the needle yet again to get an etching underneath her breast and another behind her ear from Brazilian tattoo artist, Daniel Tucci, during her trip to Rio De Janerio this month.

He told a source at Yahoo! Omg: ''I drew a Number 12 in black Roman numerals about five centimetres big on her.''

''She told me that 12 is her lucky number and that's her lucky place, below her breast. The 2nd tattoo is the Southern Cross, a constellation made of five stars, which is one of the symbols of Brazil.''

''It's a cross made with stars around her ear, one star on the top of the ear, one behind, one on the back, one below and one on the tragus, like a circle around her ear.''

According to the famed tattoo artist, Cara hasn't posted any pictures online as she is keeping her latest designs top secret and she has no plans to stop adding more tattoos to her body in future.

He added: ''I have a photo of it but she asked me not to post it on Instagram before she posts it, she wants to make a surprise of it. She loves tattoos and says she isn't going to stop, she wants to be covered in tattoos.''

Cara's agent Sarah Doukas, at famed modelling agency Storm has reportedly received complaints.

The source revealed: ''Chanel have already expressed alarm at the quick succession of Cara's tattoos and Sarah has told her to call a halt to it. As far as they're aware, she has six, but no one is sure how many there really are. And with some of them in very visible positions, Chanel and Burberry have both expressed concern.''

Cara already has a number of tattoos which include 'Made in England' on her foot, a lion on her right index finger and her initials on her right hand.
