Of course, Paris, who has been open about her IVF journey, isn't the only celeb to grow her family with the help of a surrogate. Last year, Rebel Wilson welcomed her "miracle" baby through surrogacy, and Priyanka Chopra and Nick Jonas revealed they were first-time parents following the birth of daughter Malti Marie.
Priyanka, 40, recently shared how health issues prevented her from carrying their baby girl, telling "British Vogue" that surrogacy was a "necessary step" due to the "medical complications."
U.S. & World
"I'm so grateful I was in a position where I could do this," the actress shared in the Jan. 19 cover story, detailing her daughter's early arrival. "Our surrogate was so generous, kind, lovely, and funny, and she took care of this precious gift for us for six months."
As for Kim Kardashian, she also came to the conclusion that pregnancy just doesn't "really agree" with her after the birth of her first two kids North West, 9, and Saint West, 7.
"Every medical issue that you could probably have, I feel like I get, and I worry so much about it," she previously told E! News. "That's my experience and I'm not gonna pretend that it's not."
Kim, 42, and Kanye West, 45, went on to welcome Chicago, 5, and Psalm, 3, via surrogates.
The SKIMS founder also admitted it affords a level of privacy that pregnancy doesn't, saying in a 2016 episode of "Keeping Up With the Kardashians," "You could have a baby for a year and nobody would even know."
