Eminem paid tribute to fellow rapper 50 Cent during 50's Hollywood Walk of Fame ceremony on Thursday.

"Of all the things I don't remember about 2002, I have a very clear memory of the first time I met 50," Eminem told the crowd during his speech. "One of the first things I noticed when he walked into the room was his presence. It just kind of felt like he's going to be a star … He was the whole package."

Eminem is thought to be the reason that 50 was able to cross over in the mainstream. And their friendship has lasted the test of time, with there being no documented beef between the two - and we all know how 50 gets down...

But Em sang 50's praises, especially when speaking about his music:

 "And what's crazy about it to me is the charisma and the personality, everything matched the intensity of his music. [...] If it worked on us, it was going to work on the rest of the world, and I'm glad we trusted our instincts."

"I'm here today because he's not only a business partner to me, this is one of the best friends I've known in the world. I would say it's much more fun to be his friend than it is to be his enemy, 'cause this guy is f*cking relentless. And he won't stop," he continued.

 "He pretty much does it all. And he's also helped me through a lot of hard times in my own life, and he's always been there when I need him. So, 50, congrats on your star, man. Hollywood is making it official what I knew from the beginning, and Dre knew from the beginning."

50 then thanked both Eminem and Dr. Dre during his speech. "I don't honestly think my career would've been what it was without their support. Dre's a mentor for the whole squad, really, because he's been doing it for long before that and was able to guide us in ways without even knowing that he's doing it."
