Darren Hayes, since he's gay (I'm female), so I guess switching teams.. would mean switching genders for the day, or if (don't get offended) he could magically be straight for a day.
And if you are like who? He was the singer of the Australian group Savage Garden and he's now a solo artist.
*goes off to daydream*...
I would also consider Orlando Bloom, Johnny Depp, and Steven Strait (actor/model).
