In the course of a career that has spanned nearly 60 years, Willie Nelson's net worth has grown steadily as he's turned into one of the most legendary country singers of all time, and now he's about to get even richer ... by launching his own brand of marijuana!

A few weeks back, Food World News reported on the plans the singer and longtime marijuana advocate had to create his own brand of the recreational drug, Willie's Reserve, which is set to boost Willie Nelson's net worth even further - but that doesn't mean the country legend's about to slack on the job.

While there's a good chance that the business venture of Willie's Reserve will make Willie Nelson's net worth grow by a strong margin, the "Always On My Mind" singer has stated that he's committed to launching a good product that he'll be supervising on his own account.

Time Magazine reports that the first product that'll make Willie Nelson's net worth boost will be called "Willie's Weed," and it will hit the market where marijuana is already legal, namely Colorado, Washington and Alaska, in a short while.

For decades, Nelson has been one of the biggest spokespeople for the use of recreational marijuana, so the fact that he's launching his own brand comes at no surprise to those familiar with his work - and he's even known to have fun with his "stoner" image, including earlier this week (on April 20 or 4/20, namely the unofficial marijuana holiday) when he released a video alongside pal Merle Haggard of their single "It's All Going to Pot."

Last fall, Willie Nelson's net worth also made news as a set of long, redhead braids that once belonged to the singer hit an auction, with someone paying $37,000 for the musical history item.

Currently, Celebrity Net Worth lists Willie Nelson's net worth at $25 million.
