Staff Writer, BuddyTV
This week, several comedy series are making room for new and old faces. Read on to find out who's heading to your favorite shows. 

Kathy Griffin heads to Whitney: According to TV Guide, Kathy Griffin will guest star on the NBC sitcom for at least one episode. Her character Lindsay is the colleague of Whitney's friend Roxanne, and apparently, Whitney will try to get on her good side when Lindsay gets hired as Roxanne's new assistant. 

Up All Night makes room for Molly Shannon: The former SNL star will officially join the NBC comedy series as recurring character Nancy beginning early next year. Shannon's casting, which was first reported by TV Guide, will pave the way for a storyline in which her single-mom character starts dating again with the help of reluctant wingman Chris (Will Arnett).

Stroh returns for The Closer series finale: Nothing can be more fulfilling than finding "the one that got away." Billy Burke is set to reprise his role as Philip Stroh, a character introduced in season 4 as an attorney of a rape suspect but was eventually revealed to be the culprit. Unfortunately, Brenda never found enough evidence to put him away. According to TV Line, though, that might change as Brenda comes face-to-face with her legal nemesis in the final episode of the series.

The All-American Rejects to rock 90210: After N.E.R.D., DJ Samantha Ronson, Nelly, The Veronicas and Snoop Dogg, 90210 fans can expect another batch of musical performers to grace the drama series. The latest, according to AOLTV, is The All-American Rejects, who will be appearing on the January 24 episode when party-planner Naomi (AnnaLynne McCord) hires the band to entertain guests at Liam's (Matt Lanter) big party.

Eliza Dushku guest-stars on The League: The former Buffy actress will appear on Thursday's episode as Kevin's very "hands-on" Krav Maga instructor. Check out the clip for a sneak peek!
