The cat behind the curmudgeonly frown and countless internet memes has died.

Grumpy Cat, who who earned millions off that now-famous sad frown that vaulted her to celebrity, died Tuesday at age 7 from complications from a urinary tract infection, according to her owners.

Born as Tardar Sauce, the kitty’s journey to stardom began with a picture of that now-famous frown posted on Reddit in September 2012, according to her owner, Tabatha Bundesen.

That led to product endorsements (including Friskies cat food), prompted Bundesen to quit her waitressing job in Arizona to start a company to capitalize on the grumpy one’s popularity, and television appearances that ranged from “Good Morning America” to commercials.

She even drew crowds during appearances — including one at Tampa Theatre in August 2015 to promote the premiere of the video Happiness Finds Grumpy Cat.

That appearance drew more than 500 people, including a 71-year-old woman and her three grandchildren who left Savannah, Ga., at 8:15 a.m. for the nine-hour drive but still had to wait toward the back of the line.

But how do you know that you’re really reached star status? By starring in your own Christmas-themed Lifetime movie.

RIP. We’ll miss that scowl that made us smile.
