After the mum-of-two pointed out the name similarities, her friend apparently swore she 'didn't even realise'.
'Guys, we are BEST friends. She knows my children's name. She was at most of their births. I am just so perplexed by this,' she added.
'She had TONS of items that are embroidered with her name on them. This had to have been thought about well before the birth.'
'It's very strange, especially because Nix is such a unique name. I have a hard time believing she didn't make the connection beforehand. I can't imagine naming my child a combination of the names my best friend has chosen for her children. She was AT your kids' births! It's very strange!' one person commented.
When her post triggered dozens of reactions, the woman updated the story after confronting her best friend.
The friend angrily told the woman she actually named her daughter Onyx, and that Nix was simply her nickname, before hanging up.
Friendship over, it seems.
