Hilary Duff and her "Younger" co-star Nico Tortorella took bonding to new heights.

Tortorella, 30, decided to give her breast milk a try after the mother-of-two brought her breast pump along to a table read of season six of the Paramount Network series Friday.

The actor, who plays friendly tattoo artist Josh in "Younger," shared an Instagram Story of himself downing a cup of Duff's breast milk. "I'm for real doing this right now," he said during a clip captioned, "Full proof that @HilaryDuff's milk is delicious."

"Oh, my God!" a pleasantly surprised Tortorella exclaimed, as Duff held up a freshly pumped freezer bag of her breast milk in front of the camera. "Can I have some more?" he asked.

Duff also recently revealed that she consumed her placenta in a smoothie following her daughter's birth.

"It was the most delightful smoothie I’ve ever had," Duff said during an appearance on Dr. Elliot Berlin’s Informed Pregnancy podcast in November. "I haven’t had a smoothie that delightful since I was ten. It was calorie-filled with juice and fruit and everything delicious."
