Playing Serena van der Woodsen in the hit show Gossip Girl might seem like the most glamorous job in the world, but as these pics reveal, those gorgeous shoes can be tough on your feet!

Blake Lively had to take a break from her stunning crystal encrusted Christian Louboutin heels while filming the latest series of Gossip Girl yesterday, and like many of us, she chose to slip into a pair of Ugg boots to give her feet a break!

We know Blake Lively normally styles her own red carpet looks, but she told Vogue that she's having a slight rethink. She said: "Styling is a lot of work! I guess I would consider [getting a stylist] in the future. If I had a family and I was going on a press tour, I would not be spending my time [researching fashion] - I'd be getting my kids their Cheerios.

Alexa Chung is to guest star in the new series of the fashion-fabulous series Gossip Girl.
