Paris Hilton Brings Her Beau to the Playboy Mansion

Out for another night on the town, Paris Hilton stopped by the Playboy Mansion's Halloween party on Saturday (October 27).

The 31-year-old socialite opted for a whimsical fairy costume, while her boyfriend, River Viiperi, joined her in an Indian costume.

Later that evening, Paris tweeted, “#YES! @Iamdiddy killing it on the mike performing all his hits! #CirocFlowingAtThePlayboyMansion! #BestHalloweenEver! :D.”

In related news, Miss Hilton and Viiperi attended another party, where they dressed up as Alice in Wonderland and the Mad Hatter, but it looks like there are more costumes to see!

Earlier this week, the hotel heiress tweeted, “So many #Halloween parties to go to this week. Already bought 6 amazing costumes for the festivities. Have you picked out your costume yet?”
