According to TODAYshow.com, Miley, who is set to perform the song on Tuesday's "Dancing," has been warned by producers to keep things G-rated.
"Her rehearsals of the song have been fine, but the show is on live but when Adam Lambert rehearsed for the American Music Awards , he didn't do anything controversial during rehearsals, either," one source claims. "(Cyrus has) been told that she can be herself, but there'd better not be any surprises."
The report comes a week after Miley was filmed giving one of her "Last Song" producers a lap dance. The recent release of the "Can't Be Tamed," in which a highly sexualized Miley dances in a birdcage (see video below), also caused controversy.
