Christopher Knight, best known for playing middle son Peter on The Brady Bunch, admits the story of his first kiss may be difficult for some fans to wrap their heads around, given it was with his on-screen sister!
That's right, Peter and Jan (played by Eve Plumb) locked lips, but not on set, of course.
"We were on the QE2 ship in London," the 56-year-old actor tells Closer. "I found myself in her clutches and enjoying it."
Turns out, Christopher and Eve's hook-up wasn't the first Brady Bunch love connection to take place.
Barry Williams, who played oldest brother Greg on the family sitcom, not only romanced on-screen sister Marcia (Maureen McCormick) but also dated his TV mom, Florence Henderson!
And according to reports, the youngest siblings got hot and heavy, too. Susan Olsen and Mike Lookinland, who played Cindy and Bobby Brady on the series, allegedly made out in the prop doghouse!
Looks like this family had a lot of love to give!
