The Life As We Know It star called Ryan Seacrest's radio show to discuss photographs which had been featured in newspapers and magazines.
Heigl said: "The other night, my husband and I, we were chillin' in the hot tub, it was just the two of us. We had just put the baby down, it was like 8.30, 9 at night.
"He's been gone, he was on tour, he was only home for three days. I wore my most ridiculous bikini, it was awesome."
She continued: "[Our neighbour] starts screaming at us to go inside. I'm like, 'I've had it, I've had enough if this. It's ridiculous, it's harassment and I'm calling the police'. We called my security and they called the police and they went and talked to him and then came over and talked to us.
"At that point we were a couple cocktails in. That's the other thing that's so ridiculous, we were totally hanging out, like just making out in the hot tub. It was totally PG, we're not idiots. We're not gonna be out there doing anything scandalous."
Heigl joked: "So there was no noise except us talking quietly to one another, and it sounds lame, it was us listening to Josh's album. We could barely hear it; now I'm sounding defensive.
"The most hilarious [thing] is there's video footage of us in our bathing suits. We're the most boring couple in Hollywood and that's the most scandalous thing we've ever done."
