Not to beat you over the head with the Braff-Bilson hammer or anything this morning, but it seems that all my online pontificating might not completely off base. The Scoop reports:

Adam Brody and Rachel Bilson have reportedly hit a rough patch. The stars of “The O.C.” fell in love while working on the show, and it “looked like they were on their way to getting engaged just a little while back,” a source told Star, but “are going through a really difficult period right now.” One reason, according to the insider, may be because of Bilson’s friendship with Zach Braff, her co-star from “The Last Kiss.” “Zach calls Rachel a lot and they talk on the phone like girlfriends,” says the insider. "But what really eats away at Adam is when Rachel starts talking about how mature Zach is. No guy appreciates his girlfriend comparing him to another guy.”

Another Zach coming between Seth and Summer. Remember the Season Two debacle that was Zach the water polo player, what with the comic and the prom. Don't do it again, Sum.

Note to self: Must learn to differentiate between television and real life.
