How do I define relationships between User, Post and Like models

I'm building a blogging app with laravel with the functionality to like a post (only once by a user) with a thumbs-up icon. I have set up a model each for User, Post and Like with their respective tables. The likes table consist of user_id,post_id and the timestamps columns. I have also defined relationships between User and Post models like so: Inside User model:

Public function post(){
    return $this->hasMany (App\Post)
} 
Public function like(){
    return $this->hasMany (App\Like)
} 

and inside Post model;

Public function user(){
    return $this->belongsTo (App\User)
}

My challenge however is in writing a relationship between Post and Like models. What relationships will exist between both models?
