The smitten Geordie Shore star, 24, showed off her new inking on Valentine's Day with a special message to her on-off beau.
Sharing a picture of the tattoo for the first time with her Twitter and Instagram followers, Charlotte wrote: "Happy valentines........M #YoungStupidAndVeryCrazyInlove."
The new inking, just above her elbow, shows two arrows in a cross below the initial 'M'.
She also shared a photo of the pattern being inked on in a tattoo parlour in Bondi Beach, Sydney.
It's the ultimate sign of permanence from the former Celebrity Big Brother winner, who is currently on the other side of the world in Australia.
Proving that absence makes the heart grow fonder, Charlotte sent Mitch a cute message saying: "Wishing I was with my little shellfish today as its Vday but not long now 13 days and counting."
After dating for more than a year, Charlotte and Mitch initially split last summer when she admits he dumped her by text.
Now back together again, it seems the couple's relationship could be the real deal this time round and a loved-up Charlotte has even said she will love her boyfriend forever.
Speaking about her other half on This Morning recently, the star said: "I've been spending a lot of time with Mitch and I do feel like he may be my lobster.
"He's my soul mate and he's my best friend. I'll love him forever."
They recently enjoyed a holiday in New York where they confirmed their reunion with a kiss selfie.
