Kyle, 35, didn't respond, and there was no reply apologising for the text message mix-up.
The last straw was when he arrived home from a walk with daughter Marlowe, to find the nanny in the couple's bedroom.
"Kyle said the way she was peeking out of the window in our bedroom made him realize, "OK, that text was NOT a mistake."
It was at that point he recorded a conversation with the woman, who was unable to come up with a plausible excuse as to why she was in their boudoir or the sexy message.
"I'm sorry I was just messing around with a friend I didn't mean any harm," the nanny said by way of an explanation.
Needless to say the family are keen to avoid hiring anyone else right away and opted to travel together as a unit instead.

"Kyle and I put our heads together and came up with a plan. And I was so grateful in that moment for the opportunity for teamwork, because it reminded me that no pathetic and conniving woman can ever come between us," Eva wrote.
"We were going to go on Kyle's trip together. As a family. We would pack up a bunch of stuff, ship out even more, and spend some time on the East Coast where he works."
