Is Taylor on for season 4??

Taylor will probably be in season 4 it's not like they can get rid of her I think that Nate and Serena will get together and Vanessa and Dan will get together. In the commercial I saw for the sekunde part of season 3, Taylor kisses the guy who sells people drugs.

Not that I know of.

actually, now that wewe mention it, when she was talking about haiti she alisema that she was 'focusing on finishing the LAST season of gossip girl' and there is going to b 4 seasons, do maybe, i dunno...

I read on a shabiki site that she'd be on & off the onyesha to work on her band

Not at the first few episodes.
According to this source:link
"She's been looking for trouble all season long, and it looks like Jenny Humphrey is going to find it - when Gossip Girl returns inayofuata season, she won't be there.
A chanzo close to the CW soap tells EW that Taylor Momsen's character will be absent for an unspecified number of episodes at the nyota of the fourth season.
Why? The vague "creative reasons."
“When wewe watch the season finale,” the insider adds, referring to the current season, “you will see that we’re doing something very big with her character.”"

Bella, I was listening to my favourite radio station the other siku (maybe two days ago?) and they announced that Taylor quit GG after a bust-up with the producers.

Now, I don't know how legit this chanzo is, but it's one of the most maarufu stations around (Nova 96.9), and I'm pretty sure they'd do their research before telling God-knows-how-many-listeners about something they're not even sure of.

I don't really know, but we definitely won't be seeing Taylor in the first few episodes of season four.
