Emma Watson happily signs an autograph as she arrives at Pulino’s Bar and Pizzeria in NYC on Thursday evening (March 25).

The 19-year-old actress, in a stunning Christopher Kane floral and lace dress, served as co-host to the London show Rooms closing party.

Emma recently took the stage at Brown University as Olga Sergeyevna in Anton Checkov‘s Three Sisters.

According to a source at The Sun, “Emma was nervous beforehand, but she was faultless in her role. She has been juggling coursework with rehearsals and learning lines, so she’s had a lot on her plate.”

The source continued, “Emma was over the moon that every show was a full house. She also made some new friends while doing it.”
