Luke Bracey, who played troubled teen Trey Palmer on the Australian soap opera last year, is currently in Paris filming Nicole Kidman-produced romantic comedy Monte Carlo with Meester.
According to The Daily Telegraph, the couple were photographed walking around the city with their arms around each other.
Meester, who plays Blair Waldorf in the US drama series, is believed to have split from her Gossip Girl co-star Sebastian Stan in April this year.
