Food TV star Sandra Lee, who is Gov. Andrew M. Cuomo's longtime girlfriend, remained hospitalized Wednesday for a fluid buildup apparently related to her recent breast cancer surgery, according to a source with knowledge of the situation.

Cuomo left Billy Joel's concert Tuesday night at the Nassau Coliseum after 9 p.m. as Lee, 49, was taken to the hospital, the source said.

She is expected to remain in the hospital so her condition can be monitored for several days.

Lee underwent a double mastectomy on May 19 after she was diagnosed with the early stages of breast cancer.
