Celebs on the Farm stars Montana Brown, Holly Hagan and Kerry Katona have got down and dirty for the launch of the new MTV series. The cast, which also includes Blue singer Duncan James, 42, drag queen Cheryl Hole, 27, and socialite Lady Colin Campbell, 71, filmed at a real farm in the Yorkshire Dales, as they swapped red carpet glam for milking cows. Former Atomic Kitten singer Kerry, 40, admitted living in the countryside helped with her bipolar and she had 'no down days' during her two-week stint on the show.
