When the last season ended Serena and Nate parted on uncertain terms, and from what we've seen it's all change in the cast's love interests for season four.
While Ed Westwick has been cosying up to Parisian beauty Clemence Poesy, it's been confirmed that Blake will be seeing new boy on the block, Mad Men's Sam Page, leaving Chace free to pursue a new lady.
We've already seen ex-Melrose Place actress Katie Cassidy giving the more seasoned Gossip Girls a run for their money in the style stakes, and now she's been spotted muscling in on the girls’ men too.
Katie has been cast as Blair's fellow Columbia student, Juliet Sharp, and yesterday she got fully acquainted with Chace's character, as the pair shared their first kiss on set in a New York park.
This series looks set to be the most scandalous yet!
