Lorde

No, Lorde didn't risk hypothermia and dive into the harbour this weekend. But she did post this super cute throwback snap of her pal Harry, who's on his way to Duke University in North Carolina. Go large Harry!

The Bach, on the other hand, took the plunge and went for this frosty midwinter swim with his sister Harriet. Now that's hardcore.

Meanwhile, things are heating up in Maui, where Max Key and his 'bunny' (aka Amelia Finlayson) are enjoying a family holiday with the Prime Minister.

Madeleine Sami

Madeleine Sami gives her talented wife Ladyhawke a birthday shout out - and casually shows off the pair hanging with Catastrophe star Sharon Horgan. We are well jeal.

Rose Matafeo

The Jono and Ben star had an emotional weekend as she bid farewell to the house she grew up in. The Matafeo family are moving out of their Hukanui home after more than 30 years. Bless.

The Bachelor runners up continue their quest to stay relevant, hanging out together and posting pics of their super fun times. Does anyone else find it odd that none of these girls seems to have friends that pre-date the reality show?

Warriors vs. Storm with the crew ????
