Most of the time we simply post Gossip Girl spoilers as we come across them, but most are really just news items or teasers you would have figured out anyway.

This is a pretty major Gossip Girl spoiler, however.

We don't suggest reading past the jump unless you're ready for (potentially) surprising news about the show. You'll likely have strong feelings about it.

Follow the jump to read if you dare, but we hope you're sitting down ...

Chuck and Blair are breaking up, according to E! Online.

Rumors have been circulating throughout the day as it is, but the website's sources at the CW "aren't even trying" to put a good spin on this shocking twist.

Insiders say "It's a bad, bad breakup." Wow. Just wow.

Apparently, after almost a complete Season 3 of near bliss between Upper East Side soul mates Chuck Bass and Blair Waldorf, when the happy romantic scenes are finally snatched away from us, the culprit will be Chuck.

Rumor has it Chuck does "something horrible," and that everyone is going hate him for it. Jack Bass (Desmond Harrington) is also implicated in the end of Chair, which some people have suspected from the start.

No word on exactly when it will go down, but apparently it starts to unravel in either episode 17 (Inglourious Bassterds) or episode 18 (The Unblairable Lightness of Being), both of which are set to air in mid-April.

Thoughts on this shocking Gossip Girl spoiler? Any chance it's just to throw us off? Or Chair breaks up but reconciles shortly after?
