No, that's just plain silly.
Do you think that the hiring of attractive baby-sitters/nannies is affected because of the Ben Affleck (nanny scandal)?
No ... I honestly think VERY FEW things are affected by anything Ben Affleck does or says. Thankfully, the vast majority of people just don't give a damn about him, his actions, or his opinions.
I don't think she was hired to be a "Nanny". She was hired to do what she was doing and she added getting pregnant (if) plus 20 years of a guaranteed paycheck.
