Gossip Girl Scoop: Billy Baldwin Set to Return for [Spoiler Alert]

While Alec signs on for 30 Rock, his brother comes back to another NYC series

It's a good day to be a Baldwin bro!

First NBC confirmed Alec Baldwin has signed on for a seventh season of 30 Rock (hurrah!). And now, Gossip Girl sources tell me Billy Baldwin is returning to the CW series, reprising his role as Serena's (Blake Lively) father, William Van Der Woodson.

So when will we see him again and why?

Baldwin will return to the series in episode 17 of the current fifth season, set to air sometime in February. Details are under wraps, but we can tell you that "a crisis brings him back into the fold."

Dun. Dun. Dun.

And of course, we're guessing Rufus is expected to be none too pleased. Lily-Rufus fans, get ready to pounce!

Gossip Girl returns Monday, Jan. 16, with all new episodes. We finally get to see what happens after that insane, papparrazzi-triggered car crash that left Chuck's (Ed Westwick) life hanging in the balance. Bring the tissues, y'all.
