Miley Cyrus won't stop twerking, and neither will Justin Bieber and Lil' Twist.

The new song, "Twerk," which leaked three days after the "We Can't Stop" singer's racy VMA performance, features the rapper and Canadian pop star joining forces with the former Disney talent to sing about her favorite raunchy dance move.

Many industry insiders noted their disapproval of Cyrus' controversial VMA performance, from The View's Sherri Shepherd, who stated that "she's going to hell in a twerking handbasket," to the Parents Television Council criticizing MTV for "marketing sexually charged messages to young children."

Despite the backlash, the 20-year-old singer received support from American Idol alum Adam Lambert, who asked "why is everyone spazzing?" and Justin Timberlake, who said, "It's the VMAs, what did you guys expect?"

Just as the "Twerk" single made its debut Wednesday, the Oxford English Dictionary announced on its blog that the term has officially been added. Twerk, defined as a verb, means to "dance to popular music in a sexually provocative manner involving thrusting hip movements and a low, squatting stance." Other popular words added to the dictionary included emoji, selfie and srsly (short for seriously).
