TSA Wants a Closer Look at Actress Rose Byrne's Breast Milk

No one likes going through airport security. With the rules added over recent years, it can be baffling as to what is and is not allowed, especially when it comes to traveling with small children.

Actress Rose Byrne, who gave birth to her son Rocco three months ago, has been traveling a lot to promote her new films, "Neighbors 2: Sorority Rising" and "X-Men: Apocalypse." She told Stephen Colbert on "The Late Show" that when she recently took more than 3.4 ounces of breast milk (which is permitted) through security, she was stopped immediately.

"They wave this weird thing over the top of it and there's a whole production going on," said Byrne as Colbert held up a photo from the incident. "They take it very seriously that it could be something."

"I just stand there and smile and tell them that it's really breast milk and that it's nothing," Byrne continued.
