Look who swung by the Gossip Girl set today to film a surprise guest starring role — none other than GG's most punk rock ex-pat, Taylor Momsen.
Taylor is clearly reprising the role of Jenny Humphrey but nothing is known as to how long Jenny will return nor what the character's story arc might be. Taylor was given the boot from the series in 2010 and has since made devoted all her energy to her band, The Pretty Reckless.
In her time off from the CW series, she's undergone a series of headline-making antics (the latest? posing nude in a music video) and toured with Marilyn Manson, so it's a little shocking to see her in Upper East Side clothes, hanging with Blake Lively and Penn Badgley again.
