Variable parameters in C# Lambda

Is it possible to have a C# lambda/delegate that can take a variable number of parameters that can be invoked with a Dynamic-invoke?

All my attempts to use the 'params' keyword in this context have failed.

UPDATE WITH WORKING CODE FROM ANSWER:

delegate void Foo(params string[] strings);

static void Main(string[] args)                       
{
    Foo x = strings =>
    {
        foreach(string s in strings)
            Console.WriteLine(s);
    };

    //Added to make it clear how this eventually is used :)
    Delegate d = x;

    d.DynamicInvoke(new[]{new string[]{"1", "2", "3"}});
}
