Miley Cyrus is on her 60-show Bangerz tour, but it seems she may not be as prepared as she should be.

At her Las Vegas concert, Cyrus had teleprompters with the lyrics of her songs on the screen, according to the Daily Mail. She was pictured facing the screen, with lyrics to her songs lit up as the song played, similar to karaoke.

Some concertgoers were disappointed that Cyrus didn't know the words to her own songs.

"I was at Miley's Vegas concert and took these pictures because I couldn't believe she needed a teleprompter with lyrics to all of her songs throughout the entire concert," a fan at the concert told RadarOnline. "And it's not like they were just there for nothing-I caught her looking at them more than a few times!"

Her tour kicked off Valentine's Day in Vancouver.

Lately, Cyrus has made more headlines because of her antics rather than her music. 

She wears revealing one-piece outfits and continues to use her tongue as a prop. She has smoked marijuana on stage and bragged about drug use. She also made headlines when she kissed Katy Perry and a boy who invited her to prom at two different concerts. Even her choice of backup dancers has been covered in the media.

Though she has done a good job at keeping relevant, ticket sales are not going well.

There are empty seats and cheaper tickets on the secondary market, according to Forbes.

Two months ago someone could sell their ticket for more than $225, but now it's down to $182. The popularity she experienced post-VMAs made for aggressive ticket pricing, but by the time tickets were on sale, her popularity online had dropped to 80 percent, Forbes reported.
