Listen to Miley Cyrus on iHeartRadio

(Yahoo!) - Those who hate Miley Cyrus' obsession with twerking beware. The controversial "Wrecking Ball" singer has received support from Sir Mix-A-Lot, the man who wrote the anthem for women shaking their rump.

After learning that Miley spent St. Patrick's Day at a New Orleans karaoke bar performing his 1992 hit "Baby Got Back," the Seattle rapper tweeted his approval:

Footage surfaced Monday of the pop star dressed in cut off jean shorts, black tights, turtleneck and leather jacket bumping and grinding with a group of women as patrons at the Cats Meow cheered them on.

Though Miley sings along to the entire song, she does not appear in the footage until the 1:44 mark when she climbs onto the stage.

Giggling incessantly, Miley appears to be having a lot more fun than she did at the VMAs last summer.

Sir Mix-A-Lot has apparently had a change of heart since rapping that he was tired of "magazines saying flat butts are the thing." He pays homage to more voluptuous women, rapping, "A word to the thick soul sisters, I wanna get with ya."

Miley must be a true fan. The song was released in May 1992, seven months before she was born.
