Miley Cyrus Covers Beatles' 'Lucy In the Sky' at Billboard Music Awards

Miley Cyrus performs via satellite during the 2014 Billboard Music Awards at the MGM Grand Garden Arena on May 18, 2014 in Las Vegas, Nevada.

Along with the Flaming Lips' Wayne Coyne, Cyrus delivered a faithful cover of the "Sgt. Pepper's" classic.

Miley Cyrus threw fans a curveball at the 2014 Billboard Music Awards, taking on one of the greatest songs of all time instead of delving into her many "Bangerz" hits. Cyrus and the Flaming Lips leader Wayne Coyne remotely performed the Beatles' "Lucy In The Sky of Diamonds," and the cover crashed into the 2014 ceremony, which aired live on Sunday night (May 18), like a wrecking ball.

Cyrus has always demonstrated a desire to experiment with her music, and for the Billboard Music Awards, which aired live on ABC from the MGM Grand Garden Arena in Las Vegas, the pop superstar reached back in time for a grandiose rendition of the "Sgt. Pepper's Lonely Hearts Club Band" classic. With the Coyne by her side and also covered in tinsel, Cyrus presented the song with shimmering streamers, roaring instrumentation and a palpable reverence of the source material, belting out the words as confetti flew into her mouth.

At last year's Billboard Music Awards, Cyrus announced the release of an then-unreleased single, "We Can't Stop" -- and what a difference a year has made. "We Can't Stop" rejiggered Cyrus' standing in the pop universe, "Wrecking Ball" bestowed the singer with the first Hot 100 No. 1 single of her career, and the Bangerz tour rightfully celebrated a No. 1 album on the Billboard 200 chart.
