CALLER SAY WHAT?

Looks like David Burtka is on board for E!'s Foursome.

It is a Loveline 2.0-type show where 4 hosts discuss their sex-lives.

David confessed to TV Guide recently: I have quite a past......I have lots of stories to talk about."

You? Husband extraordinaire to NPH and Father-of-the-Year have "quite a past?"

For realz? Do tell......
