There's one body part that pregnant Kim Kardashian may not want to give up after birth: her lips.

The reality star tweeted a photo of her swollen lips, along with, "My pregnancy lips are outta control #IGuessNotABadProblemToHave."

Kardashian recently admitted that she has struggled to stay confident about her body with her growing curves and people's opinions about them.

"Kourtney warned me that when I got pregnant, people's opinions would be on an all-time high and people would chime in. Now I see what she means!" she told Grazia magazine, referring to her older sister Kourtney Kardashian, who has two children.

But Kardashian, 32, has also found plenty of defenders, including her younger sister Khloe, who wrote in a letter on Kim's website, " For anyone to ever criticize a woman who is growing another life inside of her is true scum in my eyes."

Pregnant "Sopranos" star Jamie-Lynn Sigler also urged critics to lay off Kardashian, telling Andy Cohen on "Watch What Happens Live," "I feel really bad for her. It's hard being pregnant."

"Your body does change," Sigler added, "I mean my boobs have like quadrupled in size and it's hard."

Kardashian, whose baby with rapper Kanye West is due in July, is not the first star to experience an enhanced pregnancy pout.

During her first pregnancy with baby Maxwell, Jessica Simpson showed off a photo of her swollen lips, tweeting "Woke up looking like the lip injection fairy visited me in the night! Is this how pregnancy face begins?! Yikes!"

Bethenny Frankel dealt with her "pregnancy face" by putting a pack of frozen veggies on her face.

"I'm a swollen beast. My face exploded," she tweeted while expecting daughter Bryn.
