Kanye West's new girlfriend Julia Fox wasn't with Kanye last night during his Donda 2 listening parties in LA.

Instead, Ye was sniffing around Kim Kardashian lookalike Chaney Jones.

And that's OK.  According to insiders who spoke to Page Six, Kanye and Fox are in an open relationship.

“Their bond transcends typical norms because they’re evolved beings who just want each other to be happy,” a Fox insider told Page Six. “There is no jealousy or bad vibes.”

While West was chatting up Chaney, Fox was back East with a mystery man.

Fox deleted all her Instagram photos of Kanye earlier this week.

She said it wasn't because of issues with Ye.

“Suddenly Instagram was not a fun place anymore,” she claimed. “I took the f*cking photos down because I read the comments and everyone was like, ‘Oh my God, you clearly only posted photos you looked good in."
