Who knew they were friends? Aussie actress is all smiles as she poses with Post Malone - but do you know who she is?

 A veteran Australian actress has stunned her fans by sharing a hilarious photo to social media of her posing with US rap star Post Malone.

Former Home and Away star Pia Whitesell, 41, shared a cheeky picture to Instagram on Wednesday which captured her having fun with the American singer.

The pair were seen grinning cheekily in the amusing snap, as Malone, 29, flipped his middle finger to the camera. 

It is unknown how Pia knows the Rockstar hitmaker, although it is possible that Malone is an associate of her multi-millionaire husband Patrick Whitesell, who is the chairman of US talent agency Endeavor.

The actress, who was born Pia Miller, played Katarina Chapman on the long-running Channel Seven soap opera Home and Away from 2015 - 2018.

Pia and Patrick were secretly wed in 2021, prompting Pia to move from her home in Australia to Patrick's mansion in Los Angeles.

He has become a loving stepdad to her two sons - Lennox, 17, and Isaiah, 21 - from previous relationships.  

It comes after Pia revealed her fitness secrets during an Instagram Q&A and said she eats healthy '70 per cent of the time'.

'You look gorgeous! Do you follow any diet or workout routine?' a fan asked.

'I try to eat well, exercise and live generally healthier 70 per cent of the time but will always leave 30 ever cent to enjoying life,' Pia responded.

Pia also previously shared her three hacks for looking naturally stunning and recommended plenty of exercise and sleep.

The star was answering a question from a fan when she said her top three tips were 'sleep, sweat and lymphatic drainage'.

She added that she likes to get that 'lymphatic system drainage' with a fascia blaster.

The Chilean-born Aussie star shared photos of herself inside a sauna using the fascia blaster on her face.

A fascia blaster is a stick-shaped massaging device designed to be rubbed against the skin to repair the connective tissue (fascia) - that causes cellulite.

The gadget is the mastermind of US entrepreneur Ashley Black, who originally used it to treat her rheumatoid arthritis, but soon discovered it also helped to diminish the appearance of cellulite.

Pia also uses the tool for lymphatic drainage massage, which promotes the movement of fluid in the body through the lymph nodes.

It is a gentle massage that uses rhythmic strokes to help assist in the removal of wastes and toxins in the body and reduce swelling.
