Jay-Z, Chris Martin and Coldplay rang in 2013 at Brooklyn's Barclays Center. VIP guests included Christina Aguilera, Victor Cruz, Jake Gyllenhaal, Adrienne Bailon and Jessica White. In front of a packed house, the rapper and rocker toasted the New Year with the help of Martin's wife, Gwyneth Paltrow, kids Apple and Moses, and singer Bridget Kelly. After the show came to an end with Jay-Z's "Empire State of Mind," the Nets part-owner and his friends hit the D'Usse Lounge backstage where they continued the celebration. Then Jay — without wife Beyoncé, who performed a private concert in Las Vegas — and Martin (sans Gwyneth, who took their kids home) headed to the 40/40 club in Manhattan where they were joined by Gyllenhaal, Michael K. Williams, Cruz and Kelly, who is Jay's backup singer. The group plus more friends headed into a private room to down Ace of Spades champagne. A spy told us, "Partygoers in the club were snapping pics with their phones as Jay and Chris walked in the front door."
