Letterman Took Mistress On A Family Vaycay!

His wife must feel like a giant a-hole!
Apparently, David Letterman felt that it was necessary to have select staff accompany him on family vacations!
And we’re sure you can guess who that staffer was – the mistress of the moment, Stephanie Birkitt!
Birkitt, who was making $200,000 a year as Letterman’s assistant, went with the late show host, his then girlfriend Regina Lasko and six-year old son to St. Barts at the height of their illicit affair.
We’re pretty sure his now wife, Regina must have been blind!
She actually believed that the much younger assistant was an innocent friend and co-worker!
But, that’s coming from the woman who waited around 23 years for a man to marry her!!!
It was even reported that the two took hikes together last fall at Letterman’s Montana ranch.
So, it wasn’t JUST about the sex?!
He should be very proud!
A clASS act!
