In an interview with PEOPLE about her two-part documentary Pretty Baby: Brooke Shields, the star spoke about finding love with her second husband, writer/director Henchy.
Shields says there was a breakup at one point sparked by her fear that she was "rebounding, or whatever they call it, because I hadn't spent any time sowing my oats." The Blue Lagoon actress adds, "I was like, 'Oh I can sow my oats now, this is what I'm going to do. I'm going to sow oats.' "
But it didn't quite turn out as she had envisioned, with Shields admitting "there was not one oat that would be sowed." The Beginning is Now founder says, "I literally got, like, rejected.… People were like, 'No, we're not going to do that.' I was like, 'Oh, okay.' "
Shields, 57, says she eventually started dating Henchy, 58, again after realizing she was talking with him every single day anyway.

"I was calling him all the time, and he said, 'You broke up with me, this is the way it works. You don't get to call me every day, because you broke up with me. So don't call me every day.' " Shields smiles as she recalls replying to the film director, "But I want to talk to you."
Henchy then told her it "doesn't work like that," and Shields remembers thinking at the time, "I don't want to lose this person, so I better behave."
