Stefanie Keenan/Getty Images for LACMA(LOS ANGELES) -- Billie Lourd opened up to fans about something they didn't know about her pregnancy -- she had a bit of a health scare.

The Scream Queens alum, who is the daughter of the late Carrie Fisher and granddaughter of the late Debbie Reynolds, opened up in a candid Q&A on her Instagram Stories on Sunday.

When a fan asked about her pregnancy cravings, Lourd explained that she had a major sweet tooth until she was forced to grab healthier food items.

Saying she first craved "Ice Cream" and shared a photo of the Ben & Jerry's flavor Mint Chocolate Cookie, the actress admitted, "But then I had a lil gestational diabetes scare" and became attached to beets.

"Random I know but that's pregnancy vibes for ya," she quipped.

Gestational diabetes affects between 2 to 10 percent of all pregnancies, reports the Centers for Disease Control and Prevention. It occurs when an expecting mom cannot produce enough insulin to give her the energy she needs and could result in high blood pressure or a larger baby that has to be delivered via C-section. Other risks include an earlier birth for the child or the mother developing type 2 diabetes later on.

Lourd also admitted during her Q&A that she hated the first trimester the most "because hormones" before cheerfully adding, "But you get through it and it's beyond worth every second of weird moods / acne / all that fun jazz when your little human arrives!!!!!!"

Lourd secretly welcomed a child, a son named Kingston, alongside fiance Austen Rydell in September.
