The Gossip Girl throwback comes shortly after news came out HBO was rebooting the series for its new streaming service. While the show will have a new young cast, there's a chance Meester and Lively could make guest appearances and reprise their original roles as Blair Waldorf and Serena van der Woodsen.
Both Lively and Meester have expressed interest in the upcoming project.
Meester told E! in May that while she hasn't heard of any reboot happening, "I never say never. So, I don't know. No one's sent me that information, it's coming from you."
Lively, meanwhile, has said multiple times she'd consider playing Serena again. "It sort of all depends," she told Variety in April 2017. "Would I do seven years of the show? No, because it's hard work and I've got my babies, and I don't want to be away from them that much. But I've just learned in life you never say never. I'm looking to do something that I haven't done yet, not something that I did. But would I do that? Who knows—if it was good, if it made sense. We had so much fun shooting and living and working in New York City."
S & B forever.
