"Gossip Girl" star Taylor Momsen has been hospitalized, according to a statement released by her doctor, Dr. Shawn S. Nasseri, on behalf of her family.

"I am writing this letter at the request of Colette Momsen, mother of Taylor Momsen," the doctor says.

"I have been treating Miss Taylor Momsen for the last few days," the health care provider continues. "She has been hospitalized for a severe, potentially life-threatening throat infection since Sunday. She has been an excellent patient, and after aggressive antibiotics and medications, she is expected to make a full recovery in the next three to five days."

Warner Brothers Television and the CW released a joint statement Wednesday in support of Momsen: "Taylor Momsen is a beloved member of our 'Gossip Girl' cast and we are happy to report she is on the road to a speedy recovery. We all look forward to her planned return to work on Friday."
