The hot AF models were spotted hanging out via a pic posted to Richie's Twitter, captioned with pink hearts.
The super hot models have been sighted together numerous times over the past few years.
They've enjoyed dinner dates, they've hit the town together and they've rocked the red carpet side-by-side looking V ~cosy~.
This Aussie star has also recently been spotted hanging out with Bella Hadid in Cannes and Sofia was recently papped on a yacht with Scott Disick.
So while it's unclear if the pair are an item or just super intimate friends, we'll defs be keeping our eyes on this one!
