A solid but not exceptional 1 million viewers tuned in to watch Barnaby Joyce and his former staffer-cum-new partner Vikki Campion's cringeworthy Seven interview on their affair and the birth of their son, Sebastian, last Sunday night.

But his eldest daughter, Bridgette Joyce, 21, was not one of them.

Instead, she took to social media to show that she was letting her hair down with a friend over a glass of wine, joking how she wished it was the Queen's birthday so they could extend their weekend.

So Bridgette would have missed the moment her father's new partner and former media adviser apologised to her, her mother Natalie and her three sisters Julia, 20, Caroline, 17, and Odette, 15, in the $150,000 interview, which they have claimed would be put into a trust-fund for Sebastian's future.
