What do the initials on Malaika Arora's pendant stand for?

Soon after Malaika Arora posted a photo of her AM intialised pendant on her social media account, netizens went into a frenzy claiming that Malaika has made her relationship with Arjun Kapoor official. Hours after her first post, she shared another photo, but this time she flipped the initials to MA and wrote MA stands for Malaika Arora, her name. So does it or does it mean something else?
