"Grey's Anatomy" star Ellen Pompeo promised she would not have a big wedding. She kept her promise.

Pompeo, who plays Dr. Meredith Grey on ABC's hit show, tied the knot with record producer Chris Ivery last Friday in a ceremonial office at City Hall, with Mayor Michael Bloomberg as a witness.

Pompeo, 38, and Ivery became engaged last November, after dating for three years. In an interview last August, she said the couple did not plan a big ceremony because "we want one thing to ourselves."

Bloomberg and Deputy Mayor Patti Harris were the two witnesses, and an official from the city clerk's office performed the ceremony, Bloomberg spokesman Stu Loeser said.
