Eminem's newest studio album 'Marshall Mathers LP 2' has just had its much anticipated release.

But why did it take three years to make?

Em recently visited a French radio station to promote the new studio set and he explained the long period of time between the release of 'LP 2' and 2010's 'Recovery'.

The 41 year-old told France's NRJ radio, "'It's basically because I'm lazy that it took so long! Now that the album is done, I'm finally going to shower."

The 'Stan' rapper revealed he spent a lot of his free time working on projects for his own record label 'Shady Records'.

He states, "I did the 'Recovery' album then I started working on some side projects for Shady Records, the label."

"I did some producing on a Yellow Wolf album and the Slaughterhouse album." Adding, "I did a collaboration album with Royce tha '59 called Bad Meets Evil. In the middle of all that I was recording for this album."

Three years was worth the wait as 'Marshall Mathers LP 2' debuts at No.1 on the US Billboard 200 chart, selling 792,000 copies.

Em's album received are the 2nd largest sales-week in 2013, it only fell behind Justin Timberlake's '20/20 Experience' as JT's album sold 968,000 in its first week of release back in May (2013).
