Kourtney Kardashian is a slave for Y2K style.

The reality star, 42, channeled Britney Spears on Instagram Tuesday, posing in the same super-short black lace Dolce & Gabbana dress the "Toxic" singer wore to the 2001 VMAs.

Both Kardashian and Spears layered a black bra and underwear beneath the sheer mini, although the former also added thigh-high lace tights to her look.

The 2001 awards show was an epic one for Spears; not only did the then-19-year-old turn heads on the red carpet, but she also made pop culture history with her "Slave 4 U" performance, which co-starred a live albino Burmese python named Banana.

It appears the 20th anniversary of one of music’s most memorable moments has been weighing on Spears, who posed in a snakeskin-print bodysuit on Instagram in June, declaring, "I held a snake at the @VMAs one time but decided to go ahead 20 years later and become the motherf—king snake myself."
