Yesterday (Aug. 30), Diddy shared a few photos of him in the studio with Dr. Dre, a big moment that he said was a long time coming.

"Yesterday, one of my biggest dreams finally came true," he wrote on Instagram. "I remember the first time I heard @DrDre’s production. It gave me clear direction on the level of Producer that I wanted to be. Last night, I got the chance to work with this man and to see his genius as he coached me through vocals."

Diddy continued by saying that Dre kind of reminded him of someone ... himself.

"He reminded me of myself, but with a different style and way more focused," he said. "I gotta step my focus up! lol But it was a great experience and I thank God for it. I hope one day ya’ll get to have the same experience with someone that you always looked up to as a hero."

Dr. Dre is currently finishing up his much-anticipated collaboration with Snoop Dogg, which the pair confirmed they were working on last month. "We're cooking up a little something" Snoop revealed. "I don't wanna talk about it too much, but we're back together again. It's been 30 years since we worked on a record, and we are doing something. We're working on something."

Since then, they've also shared photos of them working with Eminem in the studio.
