Becoming a parent is typically a life-changing experience, but Tiffany Chen probably didn’t expect those changes to include experiencing sudden facial paralysis. After giving birth to Gia Virginia Chen De Niro, who is 79-year-old dad Robert De Niro’s seventh child, in April, Chen was hit with medical complications.

In an interview with Gayle King previewed Thursday, 45-year-old Chen revealed that she was eventually diagnosed with Bell’s palsy after the birth.

"When I went home, I started to feel like my tongue felt strange," she said. "It felt a little tingly, just starting to get a little bit numb. And then I realized my face just felt weird. I didn't know what the feeling was that I was having. It felt weird."

She said that “everything was just starting to fall down on itself. Like my face was melting on itself.”

She couldn’t eat, as food was starting to fall out of her mouth, and she was slurring when she called her doctors for help. She was sent straight to the emergency room.

“I lost all facial function the minute I got into the hospital,” she said.

According to the Mayo Clinic, most people recover fully from Bell’s palsy, and people who are in their third trimester of pregnancy and up to a week postpartum, like Chen was, are among the groups more likely to be affected by the condition.

The full interview is expected to air on CBS Mornings on Friday.
