Rihanna and Drake were shackin' up and they weren't doing it in a shack!

The Queen and King of Hip Hop were holed up in a $5K/night love nest overlooking Malibu's Zuma beach for the past week and these two hardly left the building! It's not surprising, given the luxe locale ... who'd want to leave?

RiRi had her niece Majesty along for the fun and even carried the little tyke to the car on Sunday as they packed up and left. Drake was, no doubt, recovering from his back-to-back LA concert dates, where Rihanna jumped on stage and made an appearance as well.

He had plenty of comfort surrounding him as he relaxed in the $30M, 11,000-square-foot home with 8 bedrooms, a movie theater and entertainment room. Check out the pix for this swanky Airbnb pad below ...
