Something tells us we'll be watching the London Marathon in FULL this weekend...

IF there was ever a reason to watch the London Marathon in FULL this weekend, then David Gandy getting sweaty would be it.

A host of celebrities running in this year's London Marathon got together in London for a photocall today and we emitted a high-pitched scream when we saw D&G model David Gandy among them.

The seriously-sexy man-hunk, who gives us a bad case of dry mouth whenever that ad of him writhing around in a boat comes on, was posing in his full loveliness with fellow catwalker Agyness Deyn.

Even in a fluorescent-green running bib, the perfectly-chiselled heartthrob looks a-maaaazing, pulling a relaxed pose for the cameras as he stood next to Agy.

Judging by her VERY smiley face, she was the gibbering wreck we would have been if he was stood next to us - although we'd have played it a BIT cooler (we're just being mean 'cos we're well jel he had his arm round her).

Anyway, Dave and his rippling muscles and tight bottom will be joining the celeb athletes on Saturday - which also include Elen Rivas, Joe Pasquale, Dwight Yorke, Matthew Pinsent and James Cracknell.

We'll be sure to keep our eye out for him and then continually rewind and replay the moment we catch him for the rest of Saturday afternoon...
