The couple confirmed their marriage to the newspaper as they walked the red carpet at a screening for "Hope Springs" at the School of Visual Arts. They did not divulge where or when they tied the knot, however.
A source close to Tucci told the Daily News he and Blunt are planning a formal wedding in front of friends and family in the near future.
Tucci's first wife, Kate, died of breast cancer in 2009.
"Hope Spings" stars Tucci's "Prada" leading lady Meryl Streep.
