Last Friday, McMahon's wife Kelly shared in a statement: "With an open heart, I wish to share with the world that my beloved husband, Julian McMahon, died peacefully this week after a valiant effort to overcome cancer."

Born in Sydney in 1968, McMahon was the only son of former Australian Prime Minister Sir William McMahon and socialite and philanthropist Lady Sonia McMahon.

He began his career as a model, before becoming an actor in 1989 with a lead role in Australian daytime soap The Power, The Passion.

After playing soldier Benito "Ben" Lucini in Home and Away, he turned his attention to Hollywood.

Moving to the US in the 90s, he went on to star in numerous shows including supernatural TV series Charmed, where he was cast as Cole Turner and medical drama Nip/Tuck, with his performance as Dr Christian Troy earning him a Golden Globe nomination for Best Actor in 2004.

He also had roles in films including Chasing Sleep alongside Jeff Daniels and portrayed Doctor Doom in the Fantastic Four duology.

His last credit before his death was Netflix crime caper The Residence in which he played the Australian Prime Minister.

He was previously married to singer and TV personality Dannii Minogue in 1994, but they split a year-and-a-half later.

He then went on to marry Baywatch star Brooke Burns in 1999 before they divorced in 2001; the pair have a daughter together called Madison “Maddy” McMahon.

He married author Kelly Paniagua in 2014, who he is survived by.
