Kristen Stewart indulged in a "delightfully tacky, yet unrefined" meal at the Amarillo Hooters this weekend.

Munching on the restaurant's famous wings and sipping sweet tea, Stewart enjoyed her meal with a friend and tried to "keep a low profile," a source tells EnStars.

Robert Pattinson's ex went unnoticed for about 45 minutes -- until a male fan approached her table.

"When she was eating, a guy asked her if he could take a photo with her. She asked if she could take it after her meal," the onlooker said.

The Twilight star, 23, was "polite," taking photos with several fans. She eventually posed with the famous Hooters girls (above) -- and appeared to be mid-laugh in the shot. 

"She was very sweet and was chatting with the Hooters employees for a while before she left," the source said.

She reportedly told her fans not to post the photos on social media, but some just couldn't resist.

"Yeah that's just Kristen Stewart taking a picture with my little sister at hooters, NBD," one lucky onlooker wrote.

It's been nearly a month since Kristen Stewart and Robert Pattinson called it quits after more than three years of dating. A source tells E! News the actor has been talking with Stewart over the phone "from time to time," but the onetime duo has still not physically seen each other since the split.

A source told Us Weekly that Stewart and her longtime love called it quits because Pattinson never really got over Stewart's fling with director Rupert Sanders.

"They both have projects that will take them away from each other for months," added the pal. "If he can't trust her, it's impossible."

Up next, Stewart is set to join the casts of two upcoming films, Camp X-Ray and Sils Maria.  

In Camp X-Ray, Stewart will play a female soldier stationed in Guantanamo Bay who bonds with one of the prisoners. Sils Maria tells the story of an aging actress (Juliette Binoche), who stars in a revival of a play that made her famous, but opposite the young role (played by Chloe Moretz) she once had. Stewart will play a supporting part as Binoche's assistant in the Olivier Assayas-directed film.
