Jay Cutler to the rescue.

In a Season 2 teaser for her show “Very Cavallari,” Kristin Cavallari shared that hubby Cutler helped her unclog her milk ducts by “sucking harder than he’s ever sucked.”

According to Stanford Children’s Health, clogged ducts can occur in breastfeeding women if “a mother goes too long without emptying her breasts, or if insufficient milk is removed during feedings.” The issue can be eased by breastfeeding or pumping.

“You know what? Saved my life,” Cavallari added in a confessional interview.

The mom of three made the revelation at a dinner party with friends, who reacted with screams of shock.

In March, Cavallari told Page Six she “loves” that Cutler, a former NFL quarterback, has become the breakout star of her show.

“I think for both of us it’s been really nice to have people finally get to see his real personality and get to see how funny is because I mean that’s why I love him — because he’s so funny,” she said.

Cutler, 35, and Cavallari, 32, got married in 2013 and share kids Camden, 6, Jaxon, 4, and Saylor, 3.
