US supermodel Tyra Banks has spoken about her very surprising friendship with former Australian politician Julie Bishop.

The American star, 51, revealed on The Kyle and Jackie O show on Monday, she met the former Minister of Foreign Affairs, 68, through a mutual friend.

'She is amazing. She is like the Hillary Clinton of Australia,' she began.

Tyra gushed about Julie's 'warm and funny' personality and described her as 'my homegirl'.

'Through a mutual friend we had a casual dinner and this woman is like my homegirl,' Tyra explained.

'She cares about people, she's warm, she's funny and we were taking pictures. She is fun and sweet.'

Last week, Julie, who has earned the title of 'Minister of Fashion' since retiring from politics, shared photos of her dinner with Tyra on Instagram. 

 In the snapshots, Julie cozied up to the American star as they both showcased stylish outfits while enjoying a meal together at Nobu in Sydney.

'The fabulous Tyra Banks,' the ex-politician captioned her reel of photos.

Julie slipped into a stylish Zimmermann wrap dress for the occasion.

The chiffon frock flowed down her body in a muted black colour with white polka dots and long sheer sleeves.

Julie paired the piece with a basic set of black kitten heels and dangling gold earrings as she styled her short blonde locks into their usual coif.

Meanwhile, model Tyra opted for a more casual look, slipping into a pair of blue jeans layered with a cuffed black blazer.

 She covered up her long brunette tresses with a stylish, floral-patterned bandanna as she rocked a bright smile while wrapping her arm around Julie.

The former America's Next Top Model host has been living the Aussie life for the last 18 months as she jumps between her home in Los Angeles and Sydney.

For over a year now, Tyra has been preparing to launch her new ice cream store chain Smize & Dream.

She recently revealed just how she's managed to blend in with the locals.

'We'll get some breakfast in the mall, then we'll go to a Hoyts cinema,' Tyra told The Daily Telegraph.

'We'll get some ice cream at the cinema, see a movie, then we might get a foot massage. Then we'll have some lunch... Then we go to Target or Kmart.'

Tyra, who is set to open her first Smize & Dream store in Darling Harbour by midyear, went on to say she loves the Australian Kmart.

Despite walking the runway for luxury fashion houses like Saint Laurent, Chanel and Dior, the supermodel said she thinks the Kmart Down Under is 'fancy'.

She added that after a bit of shopping, she and her family will go and do the groceries.

'We'll do Coles, Woolies, Harris Farm, whatever, and so that is a whole day at the mall and we don't do that in America,' she said.

Tyra explained that the 'mall' culture in America is a dying pastime because it's just about shopping for what you 'want' instead of what you 'need'.
