Who's There: Jennifer Katharine Gates & James "Arg" Argent?

The theoretical giant red prop phone we call Who? is just ringing off the hook this week! So many good calls, and just not enough time. Here's a sneak peek at who you're talking about: Royal Wedding guests the Canadian Mulroneys (or, Mul-ROONEYS, as you claim), plus Janina Gavankar and The L Word and Casamigos. Plus, Sam Hunt? Why are Charlie Puth and Nasim Pedrad hanging out and why does the internet think Bill Gates daughter looks like Rachel Leigh Cook? Wow! What an action-packed show.
