- The final season of "Gossip Girl" will introduce a new adversary for Serena ( Blake Lively) in the form of French model/actress Zoe Aggeliki.

- Will Chase, who's coming off playing (the actor who played) Joe DiMaggio on "Smash," will combine music and sports again on USA's "Necessary Roughness." He'll play a one-time rock star who, along with a former bandmate (played by "The Bourne Identity's" Josh Hamilton), seeks Danni's ( Callie Thorne) help in advance of a reunion tour. Look for Chase's episode in the winter. [ TVLine]

TLC will follow baseball's all-time hits leader and his fiancee, Playboy model Kiana Kim, as they work through some of the tougher aspects of their relationship (he lives in Las Vegas, she's in Los Angeles) and Rose considers once again appealing his lifetime ban from baseball.
