Kendrick Lamar caused a frenzy during his gig at the iTunes Festival last night (19.09.13).

The 'Swimming Pools' rapper delivered a stellar show in London but female fans were left scrambling for safety, after a mosh pit erupted with people shoving each other aggressively to the Compton rapper's hard-hitting hip hop tracks.

Despite the commotion, Kendrick made sure to praise his loyal fans who have supported his rise to fame over the past 12 months on the back of his breakthrough album 'Good Kid, M.A.A.D City.'

The 26-year-old told the crowd: ''Everyone here knows I couldn't do this without my day one fans. Some of my most dedicated fans right here, am I right?''

After performing hits such as 'B***h Don't Kill My Vibe' and 'Poetic Justice', Kendrick - who will on Kanye West's 'Yeezus' tour in October - declared his love for London as he left the stage.

He said: ''No matter how big I get, no matter how small I get, I'll always come back to you.''

Kendrick is the latest act to take to the stage for the month-long festival which has also seen shows by Lady GaGa, Elton John and Kings of Leon.
