HOLLYWOOD, Calif. — Taylor Momsen has been battling a serious throat infection this week that required her to be hospitalized, according to Us Weekly.
The "Gossip Girl" star was released Wednesday from Cedars-Sinai Medical Center in Los Angeles, where she has been undergoing treatment.
"I have been treating Miss Taylor Momsen for the last few days," Momsen's doctor, Shawn Nasseri, told the magazine. "She has been hospitalized for a severe, potentially life-threatening throat infection since Sunday."
The 15-year-old actress was reportedly in L.A. to take a school exam when she "woke up with a sore throat."
"She thought it was just a common cold, but was advised to see an ear, nose and throat specialist before getting on a plane back to New York," a source told the magazine.
Momsen's mother flew from New York to L.A. to be with her daughter after learning of her condition.
The CW Network issued a statement saying Momsen is expected back on the set later this week.
"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," read the statement. "We all look forward to her planned return to work on Friday."
