Coming up soon, "Piers Morgan Tonight" welcomes one of the most iconic and well-respected musicians in the history of the industry, 10-time Grammy Award winner Willie Nelson.

As host Piers Morgan rolls out the red carpet for the author of "Roll Me Up and Smoke Me When I Die," the primetime exclusive interview touches upon one of Wilson's well-known favorite pastimes, smoking marijuana.

"I've got to ask you the question, have you come similarly infused today?" asks Morgan, wondering if Nelson arrived at his studio amidst his traditional herbal haze. "Did you wake up this morning and have a quick, you know, a puff?"

"I probably did," admits the guest. "If I remember. It's, you know, that short-term stuff."

Elaborating on his exploits, the 79-year-old with more than 60 studio albums to his credit reveals a seemingly unlikely character to be one of his frequent smoking buddies:

"You know, me and Snoop smoke a lot," says Nelson, talking about well-known hip-hop artist Snoop Dogg, aka Calvin Broadus. "I was in Amsterdam one time and Snoop called me and wanted me to sing on his record. And I said, 'OK.' He said, 'Where are you?' And I said, 'I'm in Amsterdam.' So he caught the next plane and come over. And we recorded a song together."

Referencing recent legislation that has legalized marijuana in certain parts of the United States, Nelson notes that such long-distance travel would no longer be required:

"Now, we can go to Colorado."

Stay tuned for scheduling details of the full interview with the father of seven, and four-time husband, whose career has spanned six decades.
