(Cover) - EN Showbiz - Blake Lively has admitted that her acting skill on Gossip Girl isn't her "best quality of work."

The 24-year-old actress will film the sixth and final season of the show this summer bringing an end to her character, tabloid diva Serena van der Woodsen.

But Blake told Bullett magazine that although she appreciates her time on her breakout show, it has not allowed her to stretch her range as a performer.

"It'll be bittersweet when it's over because it gave me all of this," she told the publication.

"I think the best way to describe it is like someone who really enjoyed high school, and is like, I'm a senior and I can't wait for the next thing!'

"Gossip Girl was so great, but what's the next challenge in life? Because, you know, six years is a long time.

"As an actor who plays a caricature of myself on the show, I don't think I'd say, Watch Gossip Girl for my best quality of work.' But I am very lucky to have had that experience."

Blake, who is currently dating her Green Lantern co-star Ryan Reynolds, will next be seen in Oliver Stone's Savages. (C) Cover Media
