Taylor Momsen is recovering from her near-fatal throat infection. "Oh, she's better," her Gossip Girl co-star, Kelly Rutherford, told Usmagazine.com at the H&M/Comme des Garcons party in NYC Thursday night. "She's good," added Rutherford (who plays Blake Lively's mom). "You know, she's young, and she's working very hard."
Rutherford, 39, blames the 15-year-old's recent hospitalization on the flu. "You know, all it takes is to get a flu, and then you work a lot of hours, and you have [a serious] flu," Rutherford explains of how quickly Momsen's illness grew severe. Added Jessica Szohr: "She's fine. "She's OK, and that's all I'm concerned about," Szohr, 23, told Us. Momsen - an Us Hot Hollywood honoree - was admitted to L.A.'s Cedars Sinai Medical Center on Sunday for a "severe, potentially life-threatening throat infection," her doctor confirmed to Us Wednesday. She returned to the Gossip Girl set Friday.
