Rita Ora and Cara Delevingne got new tattoos together last week.

'How We Do' hitmaker Rita was joined by her ''wifey'' Cara at Bang Bang McCurdy's studio in New York on Wednesday night (11.09.13) where she got an inking of a pin-up girl on her right ribcage.

Sharing her excitement about the new design, she tweeted: ''Say hello to my new little friend Rosetta...thank you @bangbangnyc she's beautiful,'' attaching a picture of her new body art.

Bushy-browed model Cara gave Rita, 22, moral support, holding her hand throughout as Bang Bangh etched the large design onto her.

describing his work, he told E! news: ''The tattoo is on her right ribcage. It's big! When she's standing it's about 7 inches tall, but when she's laying down it's about 10 inches, plus.''

Meanwhile Cara - who now has five tattoos - opted for the name of her mother, Pandora, on her left arm.

The pair spent the entire night with Bang Bang and Cara even wore a hamburger suit at one point to lighten the mood.

Bang Bang explained: ''She just pulled it out of her purse, put it on, and was like, 'Just me and my hamburger, what, what!''

She's hilarious. She's genuinely fun, one of my favourite people.''

Cara, 21, is already looking forward to her next inking, but the tattoo artists insisted she waits a while first.

He added: ''Cara actually texted me the next day and wanted to come in for another one. She really wanted me to tattoo her favourite piece of food, but I told her to wait a bit, just to see if she still wants it.''
