The reality star, 31, landed in Oz ready for her promotional tour earlier this week, but took time out to hook up with an unlikely pal in the form of Spice Girl Mel B.
The pair looked thrilled to see each other aboard the moored boat, and were later spotted deep in conversation while they caught up.
Kim later tweeted a snap of herself with the Spice Girl and her hubby Stephen Belafonte, writing: ''On a boat on the harbor with @officialmelb & @stephenthinks1'."
Entrepreneur Kim already appears to be loving the Aussie hospitality, after discovering her hotel had left pictures of new kitten Mercy in her suite.
Kim had earlier tweeted that she missed her new pet - a gift from boyfriend Kanye West - only to find framed snaps of the white Persian moggy in her hotel room.
The star tweeted: ''How cute is my hotel in Melbourne!!! They put a pic of Mercy by my bed!''
