It Ends With Us cast drama sparks new light on Blake Lively and Leighton Meester's old Gossip Girl tension

With the Internet alight over Blake Lively's tension with her It Ends with Us director and costar Justin Baldoni, fans are now looking back over rumors of drama between the A-list star and fellow actress Leighton Meester during the Gossip Girl era.

Lively, 36, and Meester, 38, headlined the CW series over its six-season run, 121-episode run from 2007-2012

The teen romance drama, which was created by Stephanie Savage and Josh Schwartz, focused on a group of wealthy teens on New York City's Upper East Side, with a gossip blogger (Kristen Bell) narrating the proceedings.

Lively and Meester played the respective roles of Serena van der Woodsen and Blair Waldorf on the series, which also featured Penn Badgley, Ed Westwick, Chace Crawford and Kelly Rutherford.

'Blake and Leighton were not friends,' executive producer Joshua Safran told Vanity Fair in an August 2017 article commemorating the 10th anniversary of the show.

He compared the actresses to their respective characters, saying, 'They were friendly, but they were not friends like Serena and Blair.'

The performers had very different personalities, Safran told the publication: 'Blake is very much in the moment. Blake knows what's happening. 

'You talk to Blake on a very contemporary level, and she would be like, "I'm doing this thing tonight. Have you been to this restaurant?"'

Meester, in contrast, had a 'very removed and very quiet' demeanor, and that 'after her scenes were done, she would wander the stage,' Safran said.

An April 2008 report from New York Magazine quoted sources that said Lively and Meester had a tendency to 'avoid each other like the plague' while filming the series.

The rivalry escalated to the point that other members at the case essentially had to 'choose sides' in the matter.

A publicist for Lively commented on the professional relationship, according to Harper's Baazar in 2017, 'Blake and Leighton have never been best friends, and never professed to be. Blake goes to work, does her job, and goes home.'

Also noteworthy in the alleged rift between the former costars are the Instagram accounts actor Penn Badgley, 37, who played Dan Humphrey on Gossip Girl, are following.

Badgley, who was romantically-involved with Lively for three years during their time as costars, was not following Lively, but both Meester and Baldoni were listed among the 297 accounts he was following as of Thursday evening.
