Can Metta make you likable?

I think somebody asked a similar question earlier and understand that this will likely be closed but hope not. Was wondering can practicing of Metta make you likeable? Or rather more approachable? Easy to talk to? This is a very strange world, there are some people who possess some kind of unexplainable magnetism, it's like people are generally attracted to them and people pay attention when they talk. They have never been out of the limelight. Is it something to do with Metta?
