One of Rev Run's daily "Words of Wisdom" messages, which he sent out to a massive email list, sparked a conversation between the two that spilled over onto the pages of a book.

"When I first got the 'Words of Wisdom' email from Rev that initiated our friendship, he was talking about marriage and cheating and that whole thing," Tyrese told Radio.com.

As the story goes, Tyrese responded to Run's "Words of Wisdom," without knowing that Run, not an autobot, was on the other end of the email.

"Tyrese had a thought to add to my words of wisdom," Rev Run explained. "He was trying to fix my word of wisdom."

Run decided to pick up the phone and reach out to the outspoken singer.
