Kendall Jenner is a dream in green as she spends the day shopping with Paris Jackson at a flea market in LA

They were reportedly introduced during Paris Fashion Week recently and have kept in touch ever since.

So Kendall Jenner and Paris Jackson decided to 'go public' with their friendship as they shopped at the Melrose Trading Post in Los Angeles on Sunday.

The 21-year-old supermodel and the daughter of the late Michael Jackson, 18, looked for vintage items, antiques and other flea market goods. 

'The girls seemed very comfortable with each other - joking around and talking a lot while shopping for records,' an eyewitness told ET. 'They were hanging out like best buds.'
