Selena Gomez is proud of her solid pack of friends. The singer shared a few photos of herself and three of her besties etching their friendship into their skin at a tattoo shop.

The new ink was acquired to celebrate a birthday and commemorate their bond that was forged through an intense history. Each of them got the number "4" drawn on various parts of their bodies.

"Best friend turned 26. Part 2. #4 because these women have stayed by my side for 7 years (@ashley_cook 12 years) 4, because you are my 4 for the rest of my life. I love you ladies. You all inspire me to be better, stronger, closer to god and we have lived the most INSANE story together already. Can’t wait for 50 more!! Ps @raquellestevens had an actual panic attack 🙄 it’s a dot! 🤦🏽‍♀️"

Gomez' second tattoo is a number "1" carved into her ribcage. This matching tattoo is for the birthday girl who also happens to be Selena's number 1 chick in her click.

"And lastly, my actual #1@courtneyjbarry you are an incredible woman. The way you handle life’s most confusing moments is indescribable and graceful. You are moved by the littlest stories to the most heartbreaking ones, you will give someone your perfume if they say you smell nice, you are freaking hilarious and always stand firm in your faith, a loving sister, an amazing friend and a beautiful daughter. You are the definition of FEARFULLY and WONDERFULLY made baby! #1"

The celebration of friendship through tattoos isn't hyped enough. It's refreshing to see women hold on to each other like this while others cover up their ink from failed romances.
