Miley Cyrus performs her song "We Can't Stop" with the Roots on "Late Night with Jimmy Fallon." October 9, 2013, 9:05 a.m. Who says Miley Cyrus is trying to escape her background in family television? On Tuesday night, the former "Hannah Montana" star took to Jimmy Fallon's late-night show to talk up her just-released "Bangerz" album, which follows a summer of nonstop controversy related to the fact that Cyrus has grown up -- gasp! -- and is now interested in many of the things other 20-year-olds are interested in. Yet old allegiances die hard, so for her performance of her song "We Can't Stop," Cyrus enlisted Fallon and his house band, the Roots, for a tribute to that squeakiest-clean of vintage TV series: "The Brady Bunch." Like Fallon's recent hook-up with Robin Thicke on another bawdy summer hit, Tuesday's a cappella rendition works to smooth out some of the edge in "We Can't Stop," in which Cyrus play-by-plays a memorable night out, complete with red cups, sweaty bodies and folks "in line in the bathroom trying to get a line in the bathroom." But it also serves as a sly rejoinder to observers who've made such a fuss over Cyrus' perceived indiscretions. Watch the Brady-ized "We Can't Stop" below.
