The beef between Tupac Shakur and the Notorious B.I.G. took some nasty turns, before both rap stars were tragically gunned down in 1996 and 1997, respectively. There were diss songs, wild accusations and rumors of a tryst between 'Pac and Biggie's then-wife Faith Evans.

'Pac dealt the first blow on his scathing diss track "Hit 'Em Up" ("You claim to be a player, but I f--ked your wife") and then Big famously addressed the rumors in his "Brooklyn's Finest" verse with Jay Z ("If Faye has twins, she'll probably have two 'Pacs"). Evans shot down all of speculation in her 2009 memoir "Keep the Faith" and once again opened up about the situation to VladTV in an interview that was published online on Tuesday.

It all started when Evans went to the studio to record on 'Pac's 1996 track "Wonda Why They Call U Bitch." She says she didn't realize that the controversial rapper was signed to Death Row, a record label which was in the middle of a beef with her parent company Bad Boy Entertainment.

"I went to the studio, I realized there were a bunch of Death Row people there, so kind of in my mind I started figuring it out right there," she told DJ Vlad.

"I didn't think that was a good look just because of the fact of the Suge and Puff situation," Evans continued, acknowledging that she was aware of the tension between the two camps that escalated at the 1995 Source Awards. "Even though I didn't really know a lot of the details about what happened, but it was clear he took a jab at Puff at the Source Awards and stuff like that. But I was pretty oblivious to the things that had gone on prior to that, until probably a few years later."

Faith admits that she felt uncomfortable in the studio, but decided to play things cool. When it was time for 'Pac to pay her the $25,000 she says she was owed, Evans went to the rapper's hotel to collect. It was there that she says Shakur asked her for oral sex.

"[He asked] in a very surprising and offensive way for sure. By that time it was pretty clear to me, it seemed to me that that was kind of like a plan," Evans explained.

"I kind of allowed myself to be played and allow myself to get into this situation, because this is totally not how I operate, that ain't how I do business and that was never up for discussion as far as that being an exchange. That's not what it was about."
