Chrissy Teigen's elegant ink collection [1] is growing. The Cravings cookbook author is one of the latest celebrities to get a sexy spine tattoo, courtesy of artist Daniel Winter [2], also known as Winter Stone. On Jan. 12, Teigen debuted the ink through a beautiful video with husband John Legend [3] guest starring. Makes sense, since her meaningful tattoo honours a song he wrote for her.

After seven years of marriage, Teigen is clearly Legend's muse. She's the inspiration behind his megahit "All of You" and more recently, prompted Legend to write a sensual new track "Ooh Laa" for his Bigger Love album. Teigen gave the song her permanent stamp of approval by getting the title tattooed on her back at John's studio.

"Working on Chrissy's new spine tattoo felt like the perfect way to celebrate the love between herself and John, and pay homage to his most recent song for her, 'Ooh Laa'," Winter told POPSUGAR. "It's been a blessing to create meaningful art for John and Chrissy over the years, this new tattoo is definitely one of my all-time favourites."

You might notice the ink matches the other tattoos Teigen and Legend share [4], like the names of their family on their arms. This font is Winterstone's signature style, and provides a beautiful cohesiveness between all of Teigen's sweet tattoos. Get a closer look at the whole process in the video above.
