Abbey Clancy is to take part in a Celebrity Kissing Booth tonight (07.07.13).
The model will be one of many famous faces manning the cubicle at BBC Television Centre in London to help raise money for Comic Relief as part of Graham Norton's 'Comic Relief Big Chat' show.
Members of the public who are over 18 and have made a text donation to the charity are free to visit and lock lips with a famous male or female celebrity live on BBC Three, though the final list of stars taking part has yet to be revealed.
Tonight's talk show will see the popular presenter attempting to break the Guinness World Record for most questions asked on a TV chat show.
His guests include Russell Tovey, Jimmy Carr, Martin Freeman, Elle Macpherson, James Nesbitt, Louis Smith and Warwick Davis.
As well as the kissing booth, providing a break from the interviews will be music from Example, Paloma Faith, Hurts and Laura Mvula.
Graham recently said it was impossible to turn down the charity challenge, especially as it wasn't as physically demanding as what other celebrities have done for good causes.
He said: "Compared to running marathons, climbing mountains and canoeing down rivers, sitting and chatting for a few hours seems quite easy.
"They are running out of people to do those physical challenges so I thought I should really get in quick with this."
The show starts at 7pm this evening.
