Paris Hilton made a triumphant — and soaking wet — return to her summer home this week, while reminding everyone why they keep paying through the nose to bring her back to Ibiza. Hilton was the main attraction Saturday night at Amnesia’s Foam & Diamonds party, where she’ll be DJing every Saturday night for the next few months. Sources say the club owner said last weekend’s opening party was the biggest money maker, so far this summer. The party reportedly went on until 7:30 AM and was capped off when Paris doused the crowd with foam from above. But the most fun part for Paris had to be the paycheck. Insiders say she’s getting $300k per gig!
