Lola on Instagram: "🎬 Fun Fact: Gossip Girl (2007–2012) – Chuck & Blair The writers originally never planned for Chuck and Blair to become the central couple of the series. Their romance started as a short-lived subplot in Season 1, but the on-screen chemistry between Ed Westwick and Leighton Meester was so strong that the producers decided to expand it. By Season 2, their relationship had become one of the show’s defining storylines."
