The show's host is a woman (from Wales) named Sarah Symonds. She's most notably known as the former mistress of prominent men such as Chef Gordon Ramsay and Lord Jeffrey Archer.
Was she a professional mistress? Yes.
Has she since kicked these men to the curb, changed her ways, and moved on? Yes.
The show 'The Mistress' is largely based here in Vancouver with only a handful of episodes taking place in Toronto. These women and their stories are real, and some of them are pretty heart-breaking. Before you jump up and yell 'HARLOT!!!!', I recommend you watch the show. You might be surprised.
Another reason I'll be watching tonight is because the very first episode was filmed at my apartment. It was a stand-in place for the actual featured mistress' home, and was merely a safety precaution for the participant. Am I genuinely excited to see my home/belongings on national TV. Yeah. Kinda sad, but true.
