Cheryl appears to drop all of her "best friend" acts the minute the series is over - Alex, Joe, Cher, they've all said that in one way or another (some more directly than others). It's true that people do naturally drift apart of course, but still. I'm surprised she and Mel have actually gone to the bother to unfollow each other though, the sounds like a falling out.

I'm more interested to hear that the Mels have unfollowed each other. So much for a Spice reunion, at this rate only Emma will be talking to Mel B.

what could those two fall out over

mel b is also very good friends with nadine coyle
