Gossip Girl's Taylor Momsen was all the talk when she unexpectedly showed up at her high school's recent Homecoming dance. Clad a black lace tunic "way too short for a dress," the Washington Post's Reliable Source column quoted a witness as saying â€” Momsen, 14, arrived with her former middle school classmates. The actress, who plays NYC rich kid Jenny Humphrey on the CW hit, spent most of the night "huddled" with them in the gym of Winston Churchill High in her hometown of Potomac, Maryland, according to the Post. "Strangers had a hard time striking up a conversation with the gorgeous blond starlet," the Post reports. (On her Facebook page, Momsen lists herself as a member of Churchill's Class of 2011, though she currently isn't attending classes.) Momsen may be spending a lot more time with her hometown chums: The writers' strike has shut down production of her show.
