Miley Cyrus gets a Vegemite tattoo inspired by Liam Hemsworth

Miley Cyrus' relationship with Liam Hemsworth has left a bitter taste in her mouth.

The "We Can't Stop" singer got a tattoo of the Australian yeast-based spread Vegemite, an odd ode to her Aussie-born fiancé.

"@MileyCyrus don't play when it comes to vegemite," celebrity tattoo artist Dr. Woo captioned an Instagram photo of the singer's new upper arm ink featuring a tiny jar of the brown food paste on Sunday.

Vegemite is a salty, rich umami flavored-spread that's typically smeared over buttered toast. It's also used as a filling for pastries.

Here's everything you need to know about this gooey condiment that's a pantry staple Down Under:

Originally produced and marketed in the U.K. as Marmite, Aussie scientists were determined to make their own when WWI put the kibosh on imports from Britain.

In 1923, a Melbourne chemist named Cyril Callister came up with Vegemite made with brewer's yeast and blended with ingredients like celery, onion and salt.

A vegemite sandwich is typically made with two slices of buttered bread, Vegemite and cheese.

Kraft Foods acquired the Vegemite brand in 1926.

During World War II, the Australian Armed Forces began buying Vegemite in bulk because of its nutritional value.

Vegemite is a rich source of B vitamins, including thiamine, riboflavin, niacin and folic acid. It does not contain fat, added sugar or animal content.

More than 22 million jars of Vegemite spread are sold every year, mostly in Australia and Commonwealth countries, with specialty stores in U.S. for about $3.20 per 5-ounce jar.

President Obama once described it as "horrible." He’s right.
