Blair and Serena don't always find it easy to be friends, given their shared past. But they do their best and deep down seem to really be fond of and caring about one another.
Teenager Jenny Humphrey (Taylor Momsen) is one of the most intriguing characters on Gossip Girl. This youngster doesn't quite know how to fit in... or how worth it it is to try.
