Alexa Chung stars in Longchamp's 20th anniversary campaign.

The 30-year-old model and television presenter features in the campaign images for the luxury brand's iconic Le Pliage bag's 20th anniversary alongside an adorable puppy.

Alexa - who also starred in Longchamp's colourful campaign for their spring 2014 collection - poses with a Le Pliage Heritage bag, which is a new, more structured version of their classic tote style.

She is joined by a white Jack Russell puppy with a brown patch on his eye for the ad, which was photographed by Max Vadakul at the breathtaking Château des Ormes resort in France.

The celebratory 20th anniversary campaign will also include an 'Alice in Wonderland'-inspired short film made by director and photographer Jean-Francois Julian.

The full campaign is scheduled for release on September 9.

Meanwhile, Alexa recently claimed she is only willing to work with brands that she loves and believes in, even if it means earning less money.

She told GLAMOUR magazine: ''It just has to be something that I like, that's it. I am offered other things which might be more money, but if it's not a brand that sits well with me then I just don't affiliate myself with it.''
