The 29-year-old rapper released his fourth studio album four years ago on Sunday (04.12.16), and to commemorate the anniversary the star has now released a hat-trick of previously unheard singles called 'Young Millionaires', 'Speech', and 'You Party'.

According to Billboard.com, the three new songs were initially slated to be featured on the record but were later scratched off the album.

The 'Black and Yellow' rapper - who has three-year-old son Sebastian with ex-wife Amber Rose - took to Instagram on Monday (05.12.16) to post three separate videos of himself smoking, each captioned with an announcement about his tracks.

He wrote: "Droppin this unreleased heater off onifc called "young millionaire" later today. Keep smokin.

"Another onifc banger might come your way tonight.

"Thought I was droppin one. Now I'm droppin 3. (sic)"

'O.N.I.F.C.' - released in 2012 - brought with it some hit singles for the rapper such as 'Work Hard, Play Hard', and even featured fellow musician The Weeknd on the single 'Remember You'.

Despite collaborating with a number of top names such as Akon, Lil' Wayne, and Ty Dolla $ign, the 'We Dem Boyz' hitmaker won't be collaborating with Kanye West on any new music as he previously said their ongoing feud - which started in January after the rapper mistakenly believed Wiz had dissed his spouse Kim Kardashian West - isn't over.

Wiz said: "We spoke on the phone [after the rant]. He apologised. I wouldn't necessarily say it's squashed though because when you see him talk about it, it doesn't add up to what he said to me on the phone.

"I don't feel like I really went at him. That was his bad."
