Charmed
Phoebe and Cole

When do-gooder witch Phoebe (Alyssa Milano) married half-human half-demon Cole (Julian McMahon) there was no way they'd be bogged down in domesticity - certainly not with Cole holdaing demon meetings in their dining room, while Phoebe was expecting their devil baby! The short-lived marriage went up in a puff of smoke when Phoebe decided that vapourising her evil hubby was for the best.
