Chrissy Teigen's tongue is "falling off" because she's eating too much "sour candy".
The pregnant star - who is expecting her third child with husband John Legend - showed what seemed to be bits of peeling skin from her tongue in a social media video, as she warned her following not to watch it if they're "squeamish".
Speaking on her Instagram Stories, Chrissy said: "I told you I'm eating so much sour candy that my tongue is falling off.
"Look at this ... It's literally falling off because I eat so much in the night. I eat sour straws.
"I suck on them and then after them, I have my Blow Pops. It's just falling off, my tongue."
The 34-year-old model admitted she's actually found it difficult to eat her lunch because of how "painful" her tongue is.
She explained: "I'm trying to eat my noodles, but it's so painful ... It's hard to eat anything hot, spicy especially.
"I don't know how to eat it. I think I'll have to put saran wrap on my tongue or something, like a tongue condom of some sort. It hurts."
Chrissy - who has Luna, four, and Miles, two, with John - revealed her love for sour treats over the weekend as she asked her followers for recommendations.
She tweeted: "I am a crazy candy freak and while I prefer sour, I'm open to anything.
"Are there any lesser-known candies you guys I think I should be eating? peanut butter take 5 was extremely eye opening for me. (sic)"
Meanwhile, Chrissy recently opened up on her pregnancy struggles, revealing she's been experiencing some sleepless nights.
She wrote on Twitter: "Still awake like it's nothing. 530am! Didn't happen with other pregnancies :( gotta work tomorrow (today) and I'm up and happy and quite alert (sic)"
