Tweed says on Twitter that the couple didn't register for their Oct. 1 nuptials and are asking "peeps" to give to the Saskatoon SPCA.
The former Playboy model says the couple has enough china.
The SPCA tweeted that it's humbled and delighted to be part of the special day.
Tweed was born in Newfoundland, but raised in Saskatoon and filmed an episode of the TV series "Gene Simmons' Family Jewels" in the Prairie city.
This isn't the first time Tweed has helped the Saskatoon SPCA — she made a $10,000 donation in July after hearing the story of two dogs who survived being shot.Suggest a correction
