Gossip Girl fans will be well aware that Leighton Meester's Blair Waldorf and Blake Lively's Serena van der Woodsen played on-screen best friends for the best part of a decade, with Blake using the show to springboard to stardom while Leighton took a laid-back approach to fame.

Sources close to the Gossip Girl actors (pictured as Blair Waldorf and Serena van der Woodsen) said the pair were not friends during filming.
Gossip Girl fans enjoyed a partial reunion with Kirsten Bell and Leighton at the SAG Awards (pictured).
In the years following Gossip Girl, which concluded in 2012, Blake lived life in the spotlight, marrying Deadpool actor Ryan Reynolds, starring in blockbusters such as The Age of Adaline, and mingling with A-Listers like Taylor Swift.
