The 49-year-old singer was feeling the love on Throwback Thursday.

Gwen Stefani was feeling all sorts of nostalgic on Throwback Thursday.

The 49-year-old singer started thinking back to when she first started dating Blake Shelton when the two were both coaches on The Voice. Stefani  posted a photo of the two smiling at one another in passing, and captioned the cute pic: "#ticktock #timeflies @blakeshelton #bestie ❤️ gx"

In the image, the No Doubt front woman is sporting a patent leather dress that she wore when she, Shelton and fellow Voice coaches at the time, Adam Levine and Pharrell Williams, appeared on The Tonight Show Starring Jimmy Fallon on Oct. 26, 2015.

The pic appears to have been taken not long before Stefani and Shelton announced they were an item. Since then, the two haven't stopped gushing over one another.

Earlier this month, the couple showed up to the Academy of Country Music Awards, and Stefani proudly shared a photo of her and the 42-year-old country crooner, writing: "So proud to be this beautiful human’s date at the ACM awards tonight."

The feelings are certainly mutual. When ET asked Shelton if Stefani was his "forever" person, he exclaimed, "I would like to think so, come on. This is romance around here, of course!"
