A gaggle of socials headed to the New York City Ballet Spring Gala from the Mark Hotel on Thursday night noticed Leonardo DiCaprio hanging outside with rapper Q-Tip.

“There were so many cars slowing down to get a look at Leo, he and Q-Tip had to go back inside,” a spy said of the actor and rapper, who are developing a TV series. “Leo asked one woman getting into her car where she was going, and told her she looked beautiful. She said the ballet.”

At the gala at the David H. Koch Theater were Alicia Keys and Swizz Beatz, Valentino Garavani, Leonard Lauder, David and Julia Koch, Kristen Bell, Fe Fendi, fashion designer Prabal Gurung and National Museum of Dance board president Michele Riggi.
