Turns out that this little TV show she's involved with is filming its series finale on the very same day.
'It's our final five days,' of Gossip Girl shooting, she told Fashionista.com. 'Every single one of the characters is in every scene. There's no room for them to change the schedule.'
We're sure she's disappointed, considering that at last month's ELLE Style Awards, Lively called shooting her Chanel handbag campaign 'a dream come true.'
Instead of attending the show, ELLE's Best TV Star is flying to Paris to host a dinner for the brand this weekend. 'And hopefully Karl will give me a sneak peek of the show beforehand,' she said.
With charm like that, how could he decline?
