Dame Edna Everage is getting into bed with pyjama king Peter Alexander for a new campaign.

The national treasure and mother-of-three is the face of the sleepwwear designer's Mother's Day collection.

The lilac-haired housewife from Moonee Ponds will join other super mums for the campaign, including Julie Burgess and her rugby league star sons, George and Tom, model and new mum Louise van der Vorst.

Everage and Alexander will appear at the official launch on today at Melbourne's Emporium shopping centre.
