Chrissy Teigen has swollen lips.
The 33-year-old Sports Illustrated model feels like her mouth is "about to explode" after she suffered a flare up of the autoimmune condition Angioedema - the swelling of the deeper layers of the skin caused by a build-up of fluid - which she believes is a result of altitude sickness from flying from Los Angeles to Utah.
Taking to her Twitter account, the brunette beauty uploaded a close-up photograph of her puffy pout and wrote: "very upset and saddened that my own birth state, Utah, has chosen to poison me with terrible altitude sickness.
"did u know angioedema can be triggered from altitude sickness? learn something new every day! my lip about to explode. goodbye world
"It's so big it's shiny and hard like glass (sic)."
Chrissy isn't afraid to give her fans a close-up view of her body as just last week she shared a video of her getting Botox in her armpits by Dr. Jason Diamond.
She wrote over a clip of her being injected: "@drjasondiamond is my favorite human. "BOTOXED MY ARMPITS.
"TRULY BEST MOVE I HAVE EVER MADE.
"I can wear silk again without soaking woohoo! (sic)"
In the video, the 'Lip Sync Battle' star - who has Luna, three, and Miles, 14 months, with 'All of Me' hitmaker husband John Legend - shared how painless it was and breathed a sigh of relief as she admitted she was scared.
She said: "That really isn't anything.
"It looked very frightening."
And the doctor told her: "That's it."
Although it was her first time having Botox under her arms, Chrissy previously revealed she had her armpit "sucked out" to make her "feel better in dresses".
She shared: "I had an armpit sucked out, which was one of the best things.
"It's a big secret, but I don't care.
"It was nine years ago or so.
"And I had two inches to my armpit. Now it's back though, so now I've gotta pay for [liposuction] again."
However, Chrissy admitted that it was "the dumbest" thing she's ever done.
She explained: "It was so easy. It made me feel better in dresses; I felt more confident. It was the dumbest, stupidest thing I've ever done. The dumbest, but I like it, whatever. I have no regrets, honestly."
