Blake Lively recalls embarrassing moment she accidentally flashed fans in a sheer top

Blake Lively relayed a story of sheer terror on Thursday while appearing on The Tonight Show.

The 31-year-old actress told host Jimmy Fallon, 43, that she didn’t know her top was totally transparent at the recent NYC screening of her new movie A Simple Favor.

Blake said she had a ‘look of horror’ after finding out that she was accidentally flashing.

‘I didn’t realize it was see-through,’ she said.

‘You didn’t realize?,’ Jimmy asked incredulously during the episode taped in Central Park.

Blake explained that camera flash caused the transparency and she quickly fixed it with tape.

The Gossip Girl star said that after ‘freaking out’ she still remained aware of it and was self-conscious that people were staring.

The actress said she then heard a man calling out to her, ‘Blake, Blake your teets are amazing’ and a woman next to him confirmed that they were.

She admitted to being confused before figuring out the man was saying my ‘tweets are amazing’ after a recent hilarious Twitter exchange with husband Ryan Reynolds, 41.

Blake was on the chat show promoting the black comedy mystery directed by Paul Feig, 55, and co-starring Anna Kendrick, 33.

She described the movie as ‘over the top and campy and trashy and fun, kind of like my outfit at the premiere.’

A Simple Favor opened on Friday and has been well received by critics.

Blake and Ryan have a three-year-old daughter James and 18-month-old daughter Inez together.
