Miranda Lambert is sporting new ink! The singer got matching eighth note tattoos with good friends and touring partners Gwen Sebastian and RaeLynn over the weekend, sharing the first picture via Instagram Saturday night (Feb. 28).

"I love @raelynnofficial and @gwensebastian! Inked in perfect harmony," Lambert writes. "Thank you Brookside Tattoo! #sisterink #TattoosInTulsa #certifiedplatinumtour"

The "God Made Girls" singer and Sebastian also shared the photo, using similar captions. The Tulsa, Okla. date was the last on the Certified Platinum Tour for RaeLynn. Sunny Sweeney will fill her spot opening alongside Justin Moore when Lambert returns to the tour on March 6 in Oklahoma City.

The "perfect harmony" tattoo adds to Lambert's canvas, but we're pretty sure she still has more dogs than tattoos. A double six-shooter with wings that rests on her left forearm inspired her logo. She's previously admitted that her father is not a fan of that one.

In May 2011, Lambert got a paw print tattoo on top of her right foot to pay tribute to her MuttNation Foundation charity. If she's sporting more ink than that, it's only for husband Blake Shelton to see.

Lambert has tour dates scheduled through early August, including stops at the Houston Rodeo on Thursday (March 5) and WE Fest in Detroit Lakes, Minn. on August 7. The current single from her Platinum album is "Little Red Wagon." The album won the Grammy for Best Country Album on Feb. 8.
