Kreayshawn and V Nasty with Redfoo and the Party Rock crew at Lavo.

Lavo kicked off the new year on Sunday with a Hungover and Broke party hosted by Kreayshawn, who surprised the crowd with her song “Gucci, Gucci.” She was joined on stage by Vanessa “V-Nasty” Reece and happily posed for photos with fans throughout the night.

Mark Foster from Foster the People was spotted dining at Lavo at the Palazzo with Emile Hirsch.

Kaskade was also spotted dining at Lavo, refueling from his New Year’s Eve set at Marquee at the Cosmopolitan, where he spun for the first 12 hours of 2012, a personal Kaskade record. The star DJ stayed at Marquee for 30 minutes after his set ended at noon on Jan. 1 to sign autographs for those who stayed until the end, and then took a group photo, which he tweeted out. After his dinner at Lavo, he headed up to the club.

Redfoo and the Party Rock crew also feasted at Lavo before hitting the club, where they were surprised with a cake celebrating their song “Sexy and I Know It” hitting No. 1 on the charts.

Later in the night, Wilmer Valderrama joined the party in the club and wasted no time getting into the booth with DJ Eric DLux and taking over the mic. He emceed for a bit, even getting the crowd to recreate a New Year’s Eve countdown.
