When a retinue of waiters hoisting champagne and sparklers parted the crowd at the Angel Ball after-party at 1Oak — and the deejay intoned, “23 bottles of Cristal for Lindsay Lohan‘s 23rd birthday” — the starlet looked startled. A half-hour later, 23 more bottles were paraded around. When someone congratulated her, Lohan laughed, “I don’t know why they are doing this. My birthday is July 2nd.” It was unclear who sprang for the bubbly, but suspicion fell on the mysterious Malaysian who earlier at the ball bid $100,000 for Lorraine Schwartz diamond earrings and a Birkin bag. Denise Rich raised $4 million for cancer research. The 900 guests at Cipriani Wall Street included U.A.E. Ambassador Yousef al-Otaiba, Evelyn and Leonard Lauder, Star Jones, Howard and Beth Stern, Natalie Cole, Brit singer Estelle and lovebirds Penn Badgley and Blake Lively. Robin Thicke performed, and a little birdie whispered his stunning wife, Paula Patton, may soon be visited by a big birdie.
