Is TH the first non-musician that she's been 'connected' with?
I think his appeal is definitely the 'Bond' esque English gentleman thing, it must seem so exotic to your average American.
Being cynical, it could also be another dig at CH - as in "Oh I have ANOTHER British man, but this one's way posher and classier than you!"
If he didn't have the Bond-buzz about him, she wouldn't have touched him with a barge pole. And once Bond is decided and it's not him (because he's fucked up his image royally with this stunt) I reckon she'll drop him like a shitty stone.
I am now officially over invested in this saga.
