Is there any way to get product with his last price in laravel

I'm trying to get product with his last price (price with last created_at)

I have :

product table:

-id

-name

-created_at

-updated_at

prooduct_prices table:

-id

-product_id

-price

-created_at

-updated_at

in Product model :

public function prices(){
    return $this->hasMany('App\Product_price' , 'product_id', 'id');
}

in product_price model:

public function product()
{
    return $this->belongsTo('App\Product' ,  'product_id');
}

on ProductController.php:

public function GetALlProducts()
    {

        $products = new Product;
        $products = $products->with('prices');

       $products = $products->get();
        return response()->json($products);
    }

I received all products with all their prices and i don't want this
