Lil Wayne -- Sued By Jet Company -- We Got You High ... And You Stiffed Us

Lil Wayne made a deal to get high for $55,000 a month ... but the jet company that accommodated him claims when it came time to pay the rapper flew the coop.

A jet company has sued Wayne and Young Money Entertainment for a million bucks ... claiming in new docs ... it leased them a G-1159B Gulfstream jet for $55K a month plus maintenance and landing fees.

The jet company says it's especially galling ... because it even customized the jet to accommodate Wayne's "unique lifestyle preferences" -- satellite phones, a custom bed, and medical equipment.

Young Money made payments for a year ... then suddenly stopped.

The lawsuit schools Wayne on the cost of living an opulent lifestyle, saying, "He appears to enjoy the finer things in life: expensive cars, a mansion in La Gorce Country Club on Miami Beach, and private aircraft travel ... naturally the enjoyment of such luxuries is not free."
