With an estimated net worth of $700 million, Dr. Dre is one of the wealthiest men in hip-hop. Only Diddy, with an estimated wealth of $735 million, is worth more.

According to Forbes, Dr. Dre earned a whopping $620 million before taxes in 2014, the biggest paycheck of any entertainer in history.

Apple acquired Beats Music and Beats Electronics, the music company Dre started with Jimmy Iovine in 2008, for $3 billion in May 2014.

In honor of the anniversary, we’re taking a look at how the fabulously wealthy rapper spends his millions.

Last summer, rapper Xzibit shared photos from a vacation he took with Dre and Threatt. A group of friends spent more than a week sailing around the Mediterranean on a private yacht.

Guests enjoyed a large spread of food on the deck.

And, of course, the views were amazing.
