The Fashion Police presenter shared pictures of her new inking, showing her in the tattoo chair and posing for a snap after the session.
The 29-year-old shared a photo with the caption: ‘#oops what did I do tonight?’
She then shared a picture posing with her tattoo artists, captioning it with: ‘Thank you @dr_woo_ssc it's magic what you can do! □@shamrocksocialclub.’
She then wrote: ‘First female member of the #ShamrockCrew thank you @Dr_woo_ssc for head tattoo.’
Kelly has been experimenting with her style since her split from fiancé, Matthew Mosshart, earlier this year.
The couple split amicably in January after being together for nearly 3 years. Kelly and vegan chef Matthew met at friend Kate Moss’s wedding to musician Jamie Hince.
Kelly has since been linked to P Diddy's stepson Quincy Combs.
A source told a US magazine that Kelly is currently enjoying single life and ‘having fun.’
They said: ‘Kelly is single, but she's having a lot of fun. She's been hooking up with Quincy, her really good friend lately...’
‘It's not serious but he's really hot and he's very into her!’
What do you think of Kelly’s new tattoo?
