Florence Welch recently revealed she and Blake go way back:
"[Blake] actually came to our very first New York show. She's been to all of the shows that we've done in America and she flew out to Las Vegas just because I was performing there over the New Year."
In fact, Blake's the one responsible for booking Flo on Gossip Girl.
The redhead adds:
"She asked if I wanted to come on Gossip Girl and so we were already friends. I love Blake. She's a great girl!"
Thanks Serena van der Woodsen!
