The Hard Rock took away the Palms’ pet guido. Pauly D signed on for an exclusive residency on the property. His first gig will be at Vanity on Feb. 18, and he’ll spin for the Rehab opener April 22. …Speaking of pools, the Tropicana has finished de-Nikkifying the property, and will call the former Beach spot SPF. To go with RPM. They can save a ton on signage if they’d really commit and start going by TRP. It’s working for LVH. … When Tiësto officially launched his residency Feb. 4 at XS, he was joined onstage by his fellow countryman Afrojack’s new girl, Paris Hilton. Her new phase as EDM attention-whore continues in full swing. The Dutch must be unfailingly polite to not want her out of the way while they’re working. We’d love to see what happened if she jumped in the booth when a DJ from Philly was spinning. Mostly because we enjoy watching people get pelted with batteries.
