Diddy at Toffee Park Adventure Playground And Youth Centre helping volunteers for Orange Rock Corp on July 11, 2011 in London, England.

*Sean Combs helped a group of young volunteers during his trip to London on Monday by painting a display in an adventure playground.

The rapper joined 50 helpers at the Toffee Park Adventure Playground and Youth Centre ahead of his concert at Wembley Arena on Monday night, reports WENN.

The kids were taking part in the Orange RockCorps program, where volunteers are given free tickets to music concerts in exchange for four hours of community work.

Diddy sported a black suit as he helped decorate the site, which was created 20 years ago to provide a safe place for children to play.
