Sorry, just looked it up and I'd misinterpreted 'bombshell' - it was the 'shock' definition, not the 'blonde bombshell' definition
But they might be hinting at it being a 'blonde bombshell', ie Emma...
If they do only mean it in the shock sense, I wonder what it means –bombshell as in it's devastated someone's supposedly 'happy' marriage/relationship? Or that someone who was previously in straight relationships has got involved with someone of the same sex (or vice versa)?
Amys136, they've been doing Couples choice since at least last year (I can remember Ashley thingy's contempowaft). In fact it might have been going for longer, I'm not sure.
