Sarah Harding bared her bum to onlookers after she accidentally split her jumpsuit while dancing at the Walkers Bring It Back launch party on Thursday night (03.09.15).

The 'Threads' singer was left red-faced at the nostalgia themed bash when she got a bit over-enthusiastic whilst gyrating on a dance machine and tore her white pants exposing her underwear to all the other guests at Vinopolis in London.

Afterwards, Sarah said: ''I haven't danced on one of these for years and got so excited that I think I danced a little too hard - managing to rip my trousers in the process!''

Former Girls Aloud star Sarah was joined at the bash by a host of other celebrities including Joey Essex, Jodie Kidd, Louise Thompson and 'Match of the Day' host Gary Lineker - who is the star of Walkers advertising campaign.

At one point, Joey and Louise had a race on the Space Hopper Pac-Man course, but the former 'TOWIE' star lost control of his bouncer and was flung off.

Speaking about his mishap, he said ''I loved the Space Hopper! It was so much fun racing Louise but hurt a lot when I came flying off at the end. I can get very competitive!''

Jodie also convinced Gary to play dress up with her and the ex-England soccer player donned a blonde wig and black headband.

The party was held to launch Walkers new flavour campaign, Bring it Back, which is asking crisps lovers to vote for their favourite classic flavour to return to shelves.

The five flavours competing to make a comeback are Barbecue, Toasted Cheese, Lamb & Mint, Beef & Onion and Cheese & Chive.

The public has until November 1, 2015 to try the different packets and then vote for their preference at or on Facebook and Twitter using the flavour hashtags. All voters have a chance to win a £100,000 prize.
