Hip-hop mogul Sean 'Diddy' Combs refuses to pay for expensive fuel costs for his private jet - so instead travels on commercial airlines.

The rapper previously used his jet to fly across the U.S, but his acting career has taken him further afield and Combs is starting to the pay the price.

He laments the rocketing costs on a new video blog he recorded while in an airline terminal before boarding a commercial flight.

He says, "Gas prices are too motherf--king high.

"I've been flying back and forth to Los Angeles pursuing my acting career. If I fly back and forth twice a month, that's like $250,000 round trip. F--k that! I'm back on American Airlines now... and I'm in coach (economy)!"
