Of course, that doesn't stop celebrity besties like Blac Chyna and Amber Rose from doing it (and doing it right in front of the camera!). Yep, there's no love lost between these BFFS — and there's plenty go go around for the rest of Hollywood, too. Whether at an awards show, on the red carpet, or on stage, celebrity pals are more than happy to share the love. And considering today is International Kissing Day, we're just about ready to do the same. Check out the gallery below to see all the famous ladies locking lips like it ain't no thang.
