David Tennant joined a host of celebrities and sports stars in what is being dubbed as The Greatest Best Man's Speech Of All Time. The spoof video was put together for the wedding of Ross Aitken and Lindsay Lawson by Ross' brother Andy Aitken and fellow best man Graeme Mitchell.

David is seen in the video paying tribute to Ross and thanking him for stepping aside to let him take on various acting roles, he then reveals a typically naff celeb style tattoo of Ross' name on his chest and says: “He’ll always be on my heart.”

As well as being a fun memory for the couple on their big day the video raises awaremess of the Bill McLaren Foundation which raises money for kids sport. To donate go to http://ift.tt/28EiVDI
