It's CW Premiere Week!

The weather may be cooling down outside your front door, but things inside your living room are about to get hotter than ever.

That's because The CW kicks off its 2011-2012 season this week, airing a slew of season and series premieres. We were fortunate enough to be on hand at the network's Bing-sponsored premiere party in Burbank on Saturday night, and we've posted a bunch of pictures below from the event.

Click through now, as stars from various shows came together, and then fire up that DVR. We've included the week's premiere schedule after the photos. (Note: All episodes/programs to be covered in-depth by TV Fanatic.)
