Read Khloé Kardashian's Lips: She Didn't Get Fillers

The Kardashians have played the fame game long enough to know when to stay silent on gossip and when to stage a public defense of all the hearsay. With the season 15 premiere upon us, Khloé Kardashian took to Instagram with a "PSA" for fans. Her lips may look bigger this season, she explained via Instagram Stories, but the culprit isn't lip injections — it's her baby girl True.

"PSA I was pregnant during the entire season of KUWTK," she wrote in a note to fans via Instagram Stories. "Some women get 'pregnancy lips.' I was one of them. So my lips look crazy and massive. Trust me I know and I HATED IT!"

"A lot of wild sh-t happens to your body and face while pregnant. It's out of our control," she wrote. "Most people don't have to film during an entire pregnancy so just watch the show and be kind about my growing body and lips. Pregnant women should be off limits." As she rightly points out, most expectant mothers don't spend their pregnancy in front of a reality TV show camera. But regardless of whether they're in the public eye or not, policing and/or criticizing women's bodies, pregnant or not, isn't very polite or sophisticated.

"Mommy shaming" seems to have become a big topic in the Kardashian-Thompson household since baby True was born in April. Kardashian came out strong against mommy shamers in a series of tweets last month: "Women who choose 2take their time after baby, I’m so proud of you! Women who choose to work out after baby, I’m so proud of you! We all must do what’s best for US!"
