Seriously hard to make a choice... there are sooo many cool guests on that list!
SMG is due to have her baby in the fall so she'll not be appearing now. Not that I thought she would have been a choice anyway. Davids wife is due too so I'm not counting on him attending either. But would love to meet Alyson & Alexis though!
If I could choose all my fave guests, they would be :-
James Marsters
Mark Lutz
George Hertzberg (you can't have Mark without having George, it's just not done! They are hilarious together!)
Julie Benz
Clare Kramer
Juliet Landau
Mercedes MacNab
Amber Benson
Amy Acker
J August Richards
Vincent Kartheiser
Charisma Carpenter
Oh just get the bloody lot!! They're all so fantastic!! Pretty please?
