Watch Lana Del Rey sing Tammy Wynette's 'Stand By Your Man' on stage at Robert's Western World in Nashville

Lana Del Rey has a habit of popping up unannounced. Similarly, Robert's Western World is known for having superstars take their stage on a whim.

What happened Sunday was a recipe waiting to happen.

"Just another Sunday night at Robert's. You never know," the honky-tonk posted on Instagram accompanying a video of Del Rey on stage.

Del Rey joined Timbo on stage for a rendition of Tammy Wynette's "Stand By Your Man." The song ended with applause from all who were there to witness.

The New York-born singer-songwriter was spotted earlier this month all over Alabama including working at a Waffle House, in full uniform, and recording at the famous Muscle Shoals Sound Studio.

While she has no tour dates in Nashville, Del Rey has a two night appearance at Franklin's FirstBank Amphitheater on Sept. 14 and 15.
