Former deputy prime minister Barnaby Joyce and his partner Vikki Campion have reportedly sold the story of their relationship to the Seven Network for $150,000.
Mr Joyce, who urged the media to "move on" in an unpaid interview with Fairfax in February, was forced to resign to the backbench as a result of the scandal.
Seven's Sunday Night program reportedly won out in a bidding war with Nine's 60 Minutes to secure the exclusive interview.
Mr Joyce indicated late in 2017 that he had split from his wife and mother of his four daughters, Natalie.
The relationship with Ms Campion, his former staffer, became public from February 7.
The couple's son, Sebastian, was born in Armidale on April 16.
Prime Minister Malcolm Turnbull said Mr Joyce had not breached any ministerial standards because Ms Campion had not been his "partner" when she worked for him.
But Mr Turnbull went on to criticise Mr Joyce for exercising a "shocking error of judgment" before banning ministers from having sexual relationships with staff.
The scandal was fed by reporting on questions surrounding Mr Joyce's travel entitlement use, his scoring of rent-free accommodation in Armidale, and harassment allegations lodged by a Western Australian woman.
