Diplo Says Paris Hilton Rolls the Best Blunts

If there's one guy who knows about partying, it's Diplo -- who says if there's one person who knows about rolling blunts ... it's Paris Hilton.

We got the L.A. based DJ Wednesday at Think Tank Gallery, where he dished on Paris' turntable skills ... but also dropped a juicy nugget on her expertise with Swisher Sweets.

Sounds like she took a hit in Ibiza and never looked back. Who knew?
