Keck's Exclusives: How I Met Your Father

How I Met Your Mother fans know way too much about the very active sex life of Barney (Neil Patrick Harris). And now we may get to hear what goes down in the real-life relationship of Neil and partner David Burtka.

David tells me he's been cast in E!'s in-development Foursome, a sex-themed chat show that will feature David and three others. Likening the format to the syndicated radio show Loveline, David says he'll open up about his personal life, though mainly about partners pre-NPH. "I have quite a past," admits David. "I have lots of stories to talk about."

Neil's not concerned one bit; he says all the couple have done in bed since the arrival of their 5-month old twins Gideon and Harper is try to catch some zzz's. Adds Neil, "We're not getting much sleep."
