If you ask Vince Staples, Ray J is one of the greatest of all time.

In that unique mindset it would be appropriate for the Love & Hip Hop: Hollywood star to be the one cutting a rug with Tupac on the rap legend's 44th birthday, which was yesterday.

That's the same Tupac hologram which made a controversial appearance a few years ago at Coachella.

Apparently, anybody who visits Hologram USA's showroom can get down with Pac for free.

Is this pretty cool, or should they let the man rest in peace?
