Gossip Girl actress Taylor Momsen will be performing at a party for Teen Vogue.
The 16-year-old, who plays Jenny Humphrey on the TV series, fronts the band The Pretty Reckless when she's not filming for the show.
According to the New York Post, the group are due to perform tonight (8th September) at the Teen Vogue event in New York. "She's been practicing for it all week," a source told the publication.
The gig isn't the first for Momsen and band - they recently toured with The Veronicas (opening up for the Aussie siblings).
The Pretty Reckless have also inked a deal with Interscope Records and their debut album should be out this year.
