Miley Cyrus is a poor conductor


The duo also sang the songstress's best hits, like "Party in the USA" and "We Can't Stop", all while the 24-year-old was dressed in a pearl-embellished top with a troll pin.

Miley Cyrus joined James Corden for a new "Carpool Karaoke" segment and the two played a game in which she rated on a scale from 1 to 10 how high she was at various times in her life.

"You ever have moments in your life where you're like, 'What am I doing?"

Cyrus shared a humorous story to prove to Corden that she's a awful driver: she actually crashed her auto into the sound trailer of "The Voice" when she was the last to leave the set one night.

Cyrus: Ugh, I'd love to smoke some weed.

However, on the other end of the spectrum, the Voice coach says that she was a "10" when filming her music video for "Wrecking Ball". I truly would love to smoke some weed.

We all know Miley for a few things; her incredible vocals, her breakout role in "Hannah Montana", and her iconic tongue, so James couldn't help but put her to use by helping him lick his stamps. While the song has always been rumored to be about Cyrus's first breakup with Liam Hemsworth, apparently that split wasn't enough to get the star to cry on command, she had to think of something else. "Let me talk to my bosses".
