Nicki Minaj's debut album Pink Friday dropped just about seven years ago.

Nicki has some amazing features on the project -- Eminem, Kanye West, Drake, Rihanna and will.i.am -- especially for a first album.

But she didn't have a feature from Lil Wayne, who was her mentor and Young Money boss.  She spoke on his absence from the album in an interview with Complex right after it dropped.

“He really hasn’t had any involvement on it. But to be honest, the album doesn’t sound like Wayne," she said in 2010. "I mean, he’s my biggest influence, but it doesn’t sound like Wayne’s stuff. It sounds like Nicki.”

In a new Instagram post she provides another crucial detail of why Wayne was off the project: He was locked up on gun charges.

7 years ago this debut was released on the same day as Kanye’s #MBDTF [which I also appear on]. He sold half a million first week. I sold 375K first week. PF went #1 a few weeks later on the Billboard 200, breaking a record for the 1st female to do it since Ms.Lauryn Hill. - After all his love & support, my mentor Lil Wayne couldn’t be on my debut album due to a gun charge in NY. That had me fucked up @ the time. It’s now triple platinum and my final single off that album is almost DIAMOND. My fans have been the most loving, supportive, relentless people all over the world since b4 this album even dropped. Thank you. We’re about to do it all over again. Can’t wait to see you guys. Miss you so much. What was your fave off this album? 🦄 #RomansRevenge #RightThruMe #DidItOnEm #Moment4Life #Blazin #SuperBass #SaveMe #HereIAm #ImTheBest 🦄 ‼️‼️‼️ everyone gets hooks n songs already done now, all these songs I just named, (with exception of hook on super bass which I co wrote with ester) ‼️‼️‼️I not only wrote my rap, but I also wrote my own hooks.‼️‼️‼️I believe that’s why this album sounds so personal & honest.
