Vincent Fantauzzo and acclaimed actress, Asher Keddie, looked every inch the power couple as they attended the unveiling of Vincent's newest portrait.

The four-time Archibald Portrait Prize People's Choice Award winner, and Asher Keddie, and the Offsrping star looked glamorous as ever on Thursday night as they revealed the new painting, which features South African actress Charlize Theron. 

The 41-year-old beauty flaunted her decolletage in a strappy, emerald green gown with her tousled blonde locks falling onto her shoulders, whilst her 37-year-old husband looked slick in a black suit and open-buttoned shirt.

Thanks to the simplicity of the Gold Logie's accessories (a nude pair of suede heels, a delicate bracelet and some subtle earrings) the focus of her outfit was well and truly the unusual cut of her plunging neckline.

Her trademark fresh-faced makeup look was on display once again, featuring a subtle pink lip with rosy cheeks and minimal eye makeup. 

The red carpet event, which included a VIP dinner and gallery viewing, was held at the swanky Langham Hotel in Sydney.

Among the artist's displayed paintings was the painting of his radiant wife that won the Archibald People's Choice Award in 2013. 

The loved-up couple married in April last year and welcomed their son Valentino in March of this year, a little brother to Fantauzzo’s 5-year-old son Luca from a previous relationship. 

Two months ago, the talented painter joked to the hosts of Ten's hit show The Project that he was trying to convince Asher to have more kids.

'I'm working on Asher having more and more children so each year I can paint them,' he mused.

When asked in an interview with GQ how his painting of Charlize compares to that of his wife, the Melbourne-born creative revealed that, although the South African actress' painting appears quite intimate, 'the painting of Asher is actually so intimate and she’s my wife and I know her so well. I don’t think I should ever compare anyone else to Asher'.

Vincent has been announced as the 'official artistic collaborator' and ambassador of Melbourne's newest luxury apartment complex, the Capitol Grand, and will hang his portrait of Charlize in it's foyer.
