McCartney, 59, and his 34-year-old fiancee smiled bashfully for the applauding crowd Monday as they briefly spoke of their impending marriage.
McCartney said his brother Mike would be best man. Mills said she had helped make her own dress.
"I designed it, working with a couple of wonderful women," she said.
The rock star, whose mother was originally from Monaghan, added: "We are not going to worry about the rain, we are going to have a good time."
Three tents and a dance floor have been built along the side of the lake set in about 1,000 acres of grounds. There is a helicopter pad for guests who don't want to drive to the remote location near the Northern Ireland border.
McCartney and Mills a model who lost a leg in a 1993 motorcycle accident met at a charity function where she was raising money to oppose land mines.
Before her accident, Mills helped set up a refugee crisis center in the former Yugoslavia. Later, she established the Heather Mills Trust to raise money for young disabled victims of war and provide artificial limbs for land-mine victims.
The recipient of several humanitarian achievement awards, Mills advocates a land-mine ban and counsels amputees.
