... and Nina Dobrev on Gossip Girl?
If you're a fan of these CW stars, you'll love the fact that Bob Levy, executive producer of both Gossip Girl and The Vampire Diaries, wants the girls - who are real-life BFFs - to guest star on each other's shows in the future.
"I love the idea!" Levy recently said of having Nina guest star on Gossip Girl, and vice versa, with Leighton turning up on The Vampire Diaries.
"We're gonna work on that. You have my word."
The girls are up for it, too.
Leighton and Nina became friends while shooting the upcoming film The Roommate, and Dobrev would jump at the chance to visit the UES.
"Oh my god, I would love to be on Gossip Girl," she said. "It's hard because we're busy, but I would love to, and for her to be on our show."
"Leighton would make a great vampire, I think!"
We can see it - and we'd love to see Nina return the favor and play a new love interest for ... well, someone. We're open to suggestions!
