They've just wrapped up an exclusive media lunch in Sydney – and suffice to say that Kendall and Kylie are causing a SERIOUS stir in Australia.
The sisters only jetted Down Under yesterday, but already they're attracting flocks of keen as mustard fans who are eager to follow their every move as they promote their just-released collection for Forever New.
And luckily, the reality TV duo – especially Kylie – have been documenting their Aussie experiences online with particular gusto.
Indeed, the younger Ms Jenner has been Snapchatting and Instagramming whenever she's found a spare moment.
In one clip, hoards of teenage girls can be seen gathering around the sisters' car, while a second video posted by Forever New shows the rapturous welcome the girls were given at Westfield Plaza shopping centre.
Understandably, 20-year-old model Kendall and 18-year-old Kylie both wore items from their range for the Westfield launch: the former in a pretty patterned keyhole playsuit, while the latter opted for a sleek white skater dress with a mesh panel on the front.
The items are priced at €115 and €135 respectively from the label's website and yes – it ships to Ireland.
The famous family members also enjoyed a boat ride on the city's river – and with Sydney basking in 22C sunshine, we bet it was a wholly pleasant afternoon out.
An Instagram photo shared by Kylie and lovingly captioned "I'll always be here for you my sister," has now notched up 1million likes. It shows the pair resting on their boat's decking.
As to be expected, neither Ms Jenners are travelling light. As well as a serious haul of luggage, Anna McClelland from Aussie fashion website buro247.com.au shared a telling Instagram snap of the pair at the media lunch.
"Lunching with these two ladies," she wrote, adding that they had "the most insane entourage I've ever seen".
We wouldn't expect anything less!
