Actress Taylor Momsen, known for her role as Jenny Humphrey on Gossip Girl, was hospitalized earlier this week in Los Angeles with a potentially life-threatening infection in her throat. US Weekly reports:

"I have been treating Miss Taylor Momsen for the last few days," Momsen's doctor, Shawn Nasseri, tells Usmagazine.com. "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," the doctor adds.

Momsen, 15, was in L.A. to take a school exam when she "woke up with a sore throat," a source close to the actress tells Us.

"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," the source adds.

If Momsen wasn't a mere 15-years-old this is the part where I'd make a crack about what she could possibly have put in her mouth that would lead to an infection.

See what I did there? I made an inappropriate jail bait joke but pretended not to at the same time. In my defense, I totally thought she was at least seventeen eighteen. Momsen has to be the only actress on the planet who ever played a role on a TV show where she's not about 10 years older than the character she's playing.
