G-Girl, Season 5 - Episode 8: All the Pretty Sources

Serena (Blake Lively) is hard at work planning a dream bridal shower for Blair (Leighton Meester), but it should come as no surprise that Serena has to plant some false information about the shower in order to keep Blair from finding out all the details.

Chuck (Ed Westwick) and Dan (Penn Badgley) decide to spend the day together to distract themselves from the fact that they didn’t make the invite list for Blair’s shower.

Nate (Chace Crawford) and Serena find a silver bullet in Diana’s (guest star Elizabeth Hurley) war against Gossip Girl, but struggle about whether to use it or not.
