The party continues for single Leonardo DiCaprio. The “Django Unchained” star and Cameron Diaz hooked up, as pals, at the opening of hot new club Rosewood on Friday. “Miranda Kerr and a group of girlfriends were the first to show,” said a spy at the cocktail lounge, adding that models Jessica Gomes and Jessica Hart were close behind. Later, “the crowds parted when Leo entered” and he sat with Kerr and company. “He was texting until Cameron arrived,” a source said, “and it was obvious they are great friends . . . he was very excited when she came to meet him, and he got up from his table to guide her to where he was sitting.” The models then did what models do: danced on banquettes, in this case to the tunes of DJ Regg Ruck, and drank Champagne and Belvedere. At 3 a.m., DiCaprio made sure to “tip the waitresses and say thank you” before he and his posse headed out. Leo was spotted the next day at a raucous Day & Night brunch (where one loaded reveler stuffed $2,000 in singles into a fog machine). Diaz was seen dining at The Lion with a pal.
