Leighton Meester & Blake Lively: 'Gossip Girl' Paris Preview!

Leighton Meester and Blake Lively are all smiles as they film Gossip Girl on Monday (July 5) in Paris, France.

The 24-year-old actress and her 22-year-old co-star got to work on the first two episodes of Gossip Girl‘s fourth season!

The ladies looked happy to be back at work together – Blake playfully fed Leighton a Ladurée Macaron – and Leighton clearly did not appreciate the gesture from her friend!

Harry Potter actress Clemence Poesy is also set to guest star in these two episodes.

Gossip Girl is set to return Monday, September 13 on The CW!
