Rapper and producer Sean 'Puff Daddy' Combs is auctioning off a business mentoring session with himself for charity.

The music mogul and entrepreneur will meet the winning bidder in either Los Angeles or New York, and spend one hour listening to their business pitch whilst offering constructive advice and feedback.

So far, bids for his services have surpassed £19,375 on the Charity Buzz website, with all proceeds destined for the Network for Teaching Entrepreneurship, which helps educate youngsters from low-income communities.

The kind-hearted 'Coming Home' hitmaker is well known for his fundraising, but was rushed to hospital following a Playboy Mansion Party he hosted for charity in February.

According to TMZ.com, the 42-year-old was rushed to the University of California Los Angeles emergency room after his entourage became concerned about the star's health. Sources revealed he had suffered ''a massive headache'' and was treated by staff before returning home. Insiders insisted his condition was unrelated to the festivities.

Previously the music mogul had attended Clive Davis' pre-Grammy party in Beverly Hills on the Saturday night, which was held at the same hotel where Whitney Houston was found dead.
