The Gossip Girl star has admitted that her sex scene with Ben Affleck in the upcoming film The Town was “awkward”.

In an interview with Interview magazine she said, “The sex scene was really awkward. It was my first day!”

Blake also says that lots of stars aren’t as confident as they seem, adding, “We stand on these red carpets and pose in these dresses, but we’re all only so confident. It doesn’t mean we think we’re great looking or anything. It’s all a facade.”
