Laravel 5.1 ManyToMany tags on blogs not working

I have a very, very strange problem.

What I try to do is to create tags on my blog posts. Therefor I use a ManyToMany relationship.

This is a fresh installed Laravel 5.1:

routes.php

Route::get('/{id}', 'BlogController@show');

Models

Blog.php

class Blog extends Model
{
    public $timestamps = false;

    public function tags()
    {
        return $this->belongsToMany('App\Tag');
    }
}

Tag.php

class Tag extends Model
{

    public function blogs()
    {
        return $this->belongsToMany('App\Blog');
    }
}

Controller

BlogController.php

class BlogController extends Controller
{

    public function show($id)
    {
        $blog = Blog::find($id);
        return view('welcome', compact('blog'));
    }
}

Welcome.blade.php

<h1>{{ $blog->title }}</h1>

<h2>Tags</h2>

@foreach($blog->tags as $tag)
    <p>{{$tag->name}}</p>
@endforeach

All the required tables are created (blogs, tags, blog_tag) and some posts and tags are created and relations are set (attach) in blog_tag.

When I run this I get this error

Invalid argument supplied for foreach() (View: /var/www/http://ift.tt/21flEjw)

It seems that is has something to do with $blog->tags. If I change it to $blog->tagss and also change the method name in Blog.php to tagss ( public function tagss() ) it is working flawlessly...

I don't get it. I know I can simply change it to tagss or something else but I am following simple tutorials here, so this should work?

Is 'tags' a reserved word or is there something else I don't see? Again, this is a fresh Laravel Installation. What am I missing here?
