Alyssa Milano slammed a London airport after they reportedly confiscated her breast milk.

The 42-year-old actress released her frustrations with the Heathrow Airport Thursday morning in a series of tweets, revealing that her breast milk was taken away "without discussion."

Before the controversy, she shared with her followers that she had difficulty pumping on an airplane on Wednesday night. About eight hours later she followed up with a tweet revealing that 10 ounces of her breast milk had been confiscated.

"@HeathrowAirport just took my pumped breast milk away. 10 ounces. Gone. Not okay," wrote Milano, who has a 3-year-old son named Milo and a 7-month-old daughter named Elizabella Dylan.

"They said they would let the pumped milk through if I had the baby with me. Why would I need to pump if I had the baby with me????" she wrote, adding that matters were made even worse because they apparently threw it away.

According to the former "Charmed" star, her other liquids were tested but her breast milk was "taken away with no discussion." She explained that she would have divided the breast milk into different containers in order to comply with the airport's rules if she had known in advance.

In response, a representative for the airport tweeted back at the actress to explain the government regulations and why she could not keep her milk.

"Hi Alyssa. Unfortunately, without a baby present, the government requires all liquids in carry-ons to follow the 100ml rule," tweeted Heathrow.

"Sorry for any confusion caused. To confirm, if you aren't travelling with your baby, milk is subject to the 100ml/(3.4oz)," the company added.

However, that didn't settle the dispute.

".@HeathrowAirport I would have happily spread milk in different containers (which I travel with) to comply to those liquid rules," said Milano. "Instead, milk was taken away with no discussion. Shampoo, lotions, etcetera were simply tested and handed back with no issue. Makes no sense at all."
