Blake Lively has revealed the first moment she “truly felt cool”.

The former Gossip Girl star took to social media on Monday via Vogue magazine’s Twitter account to do a Q&A with fans. The Town actress dished on everything from her former television show to being in Beyoncé and Jay-Z’s Run video.

“It was the first moment in my life where I truly felt cool. It gave me a high sense of self-esteem for a good 10 min,” the 26-year-old wrote.

The music video also features Emmy Rossum, Sean Penn, Don Cheadle, Jake Gyllenhaal, Rashida Jones, Guillermo Diaz and Kidada Jones.

The blonde beauty has worked with a slew of stars including her husband Ryan Reynolds. The couple starred alongside each other in Green Lantern, which hit theatres in 2011, and married in 2012.

“In the olden days, a couple could be in every movie together, but it's just not like that anymore,” Blake told her fans. “We both wish we could go back to then, because that would be a lot of fun.”

Blake starred in the television series Gossip Girl from 2007 through 2012 with Leighton Meester, Penn Badgley, Chace Crawford and Ed Westwick.

“I miss the people that I worked with, our cast and our crew,” she shared. “But I don't miss the 16-hour days.”

The Savages actress’s favourite season of the teen drama was season one as it brought many new experiences to her life.
“It was the 1st year I lived in New York City and what a way to live in NY. It was very special and surreal,” she explained.
