Listen to Justin Bieber on iHeartRadio

Justin Bieber tripped up the lyrics for his song "Fall" at his concert in San Jose, California Wednesday night.  The pop star acknowledged the embarrassing moment on Twitter, writing:

It's the latest in a series of missteps for the 19-year-old singer whose image has taken a public beating in recent weeks following reports of alleged reckless driving and bodyguard beatdowns. 

On Monday, Bieber posted a video on Instagram making fun of himself and the scrapes and bruises he said he suffered after falling down a flight of stairs.  The singer has also been slapped with a new lawsuit.  A paparazzo claims the Biebs delivered a karate-style kick in the stomach and punched him in the face during a confrontation outside of a movie theater in Calabasas, California last year.
