It was a once a jewel of Hip Hop lore to wonder who The Notorious B.I.G. was referring to on the Life After Death cut “I Got a Story to Tell.” The song details Biggie’s sexual escapades with a certain New York Knicks player’s girlfriend. It had rap fans scratching their heads for decades as to who Biggie’s foe was.

Then Fat Joe let the cat out of the bag when he outed the late Anthony Mason as Biggie’s rival who the song is about when he appeared on ESPN’s Highly Questionable earlier this week.

Now, the Terror Squad leader says that he wishes he did not divulge the precious information to the public.

“I regret saying that,” he says in an interview with HipHopWired. “I didn’t know, I don’t know if it’s my place to say that. I just knew about it so much ’cause I knew. I don’t know if it was my place to say that. I ain’t taking nothing back, it is what it is.”

Fat Joe was close to both Biggie and Anthony Mason, who died last year from congestive heart failure. He would party with Mason and the other basketball players in the clubs during Mason’s five-season stint with the Knicks.

“I love Ant Mason,” he says. “He’s as real as it gets. He’s a respectable guy. Rest in peace. I was fucked up when Ant Mason died.”

The rapper suggests that his proximity to the situation gave him a skewed perspective of the value of the information regarding the certain someone in “I Got a Story to Tell.”

“When I did that interview, it slipped,” he says. “And I didn’t realize nobody else knew. I thought everybody knew, so when he was telling me, I was like, ‘Yeah.’ He’s like, ‘Wait a minute, breaking news!’ I’m like, ‘Oh my God.'”
