Gossip Girl star Blake Lively has admitted that she gets nervous when she is due to wear a skimpy outfit on the American teen drama.

Blake often has to wear tight and revealing clothes when playing Serena van der Woodsen but doesn’t work out or diet beforehand.

She explained to Britain’s Glamour magazine: “I do panic before I have to wear a really skimpy outfit, but I don’t have enough willpower. I had to do a scene in a bra and shorts for the first time in two years.

“On the day of the shoot, I had a pork burrito, chips and coke. Afterwards, I thought, ‘I probably shouldn’t have done that.’ But whatever.

“I have never worked out, but I know you feel better when you do so I am planning on getting a trainer.”

Blake is currently dating her co-star on the show Penn Badgley but revealed that she hated the idea of working with him when she first found out who had landed the role of Dan.

She said: “At first I was so upset that they hired him. I actually poisoned the whole cast against him. But then they noticed that he wasn’t a jerk and was actually a really nice, charming person. Almost immediately I realised that too, but it took me about a week to admit it.”
