We can't imagine a world with a different Serena or Blair!
Gossip Girl is one of the most iconic teen dramas of all time and has made most of the series' cast household names.
From Blake Lively and Leighton Meester to Chace Crawford and Penn Badgley, The CW struck gold when the show premiered back in 2007!

But what would you say if we told you Blake and Leighton weren't the network's first picks for the lead characters?!
CW Casting Director David Rapaport revealed on Tuesday that GG almost starred none other than…
Rumer Willis and Ashley Olsen!
Apparently, the teen-driven channel originally wanted big names to carry the show before being convinced to take a chance on some up-and-comers.

While we're positive Rumer and Ashley would have done great, we sure are glad Blake and Leighton ultimately landed the gig!
