Having a roo-ly good time! Kelly Osbourne goes casual while Sophie Monk dons clingy dress and heels to snap selfies with kangaroos at Taronga Zoo

She has gushed about her love of all things Australian and the close bond she has forged with fellow Australia's Got Talent judge Sophie Monk.

And on Monday, Kelly Osbourne combined the two as she visited Australia's iconic Taronga Zoo with new best friend Sophie.

The pair were seen sauntering  around the enclosures and taking selfies with the Australian wildlife, with Kelly shunning her usual high fashion for a casual ensemble, while Sophie dressed up.

Kelly, 31, seemed particularly taken by the kangaroos as she spent several minutes angling herself close to the large marsupials to take a token tourist snap.

She was also seen getting up close and personal to possums, feeding them food as they rummaged around the open enclosure.

The British IT girl shrugged off the shackles of high-fashion for the outing, instead opting for low-key cool as she meandered around the popular tourist spot to check out Australia's animals with fellow AGT judges Eddie Perfect and Ian 'Dicko' Dickson.

The former Fashion Police star flew under the radar in a comfortable all-black ensemble, choosing to cloak her figure in a pair of loose-fitting trousers which she teamed with a tank top and cardigan.

She topped off the laid back look with a pair of ubiquitous black sneakers and carried a black cane in one hand to help her amble around the lengthy distance of the park due to her broken foot.

The songstress wore her trademark lilac locks straight and shielded her face with a pair of dark sunglasses.

The daughter of legendary Black Sabbath rocker Ozzy has been in the harbour city for almost two weeks and no doubt enjoyed the relaxing sojourn to the famous north shore animal enclosure.

Meanwhile, Sophie dressed up in a chic ensemble not nearly as appropriate for a day of sight seeing.

She clad her svelte frame in a colourful short fitted dress which showcased her long, lean legs, topped off with a pair of towering blue high heels which perfectly matched her Hermes leather handbag.

She shielded her face from the glare with a pair of designer sunglasses and wore her silken blonde locks tied in a low undone plait.

The former Fashion Police host has struck up a friendship with Sophie and the pair are often seen enjoying themselves in selfies splashed across social media.

Speaking exclusively to Daily Mail Australia at the David Jones Autumn/Winter fashion launch in Sydney on last week, the American star said: ‘Her and I may wear pretty dresses and have all the eyelashes, but we’re bogans’.

She added: ‘It’s so nice to work with a woman who is not competitive, we just have so much fun. You have no idea.

Kelly admitted she had not always been as fond of the Australian star as she revealed: ‘I had seen her about in LA, but because she was so pretty I was too scared to talk to her.’

But then from the first day, it was just instant. I get on and hang out with all the judges, we were all together on Sunday.

The purple-haired star gushed: ‘I’m so lucky to work not only here in this country but with the people I work with too.’

And Kelly made it clear that she has been thoroughly enjoying her time Down Under as she said: ‘Australia’s Got Talent had been amazing. To have the balls to get up there in front of the judges is a talent in itself. I have been blown away by the talent in this country and I’m so honoured to be a part of it.’
