His knee Grow handlers need to reel their homeboy in.

Justin Bieber's week just got worse.

Following a brief hospital stay after fainting backstage, the 19-year-old pop star's preparation for a final concert in London on Friday hit a speed bump.

Bieber got into an altercation with insult-hurling paparazzi, lashing out at a photographer with a stream of expletives as he was restrained by minders.

The singer quickly took to Twitter to address the incident, which was captured by Channel 5 news, and pledged to channel his "adrenaline" into his Friday show.

"Ahhhhh! Rough morning. Trying to feel better for this show tonight but let the paps get the best of me," he posted on the social networking site.

"Sometimes when people r shoving cameras in your face all day and yelling the worst thing possible at u...well I'm human. Rough week."

The scuffle came just hours after Bieber said he was "getting better" after struggling to breathe during the previous night's concert at the O2 arena, and pledged the show would go on as planned.
