Amber Rose I'm Good with Blac Chyna Again, She's My Slut Walk Partner

Amber Rose and Blac Chyna were in lockstep at this year's Slut Walk ... which is way different from their epic feud at the last one.

Amber and a very pregnant Chyna were arm-in-arm Saturday in downtown L.A. as the crowd roared their approval ... especially for Rob Kardashian's on-again-off-again girl.

You'll recall, last year Chyna was a no-show because she was hanging with Future in ATL and didn't want to come home.
