Advancements in the world of medicine over the years has made the ability to biologically expand one's family, no matter age or medical conditions of the mother, a bit easier through the option of surrogacy.

On Wednesday, it was announced that Kim Kardashian West and Kanye West are expecting their third child in January, but were using a surrogate this time around. While this is due to a medical condition of Kardashian West’s, there are many reasons why women and couples choose surrogacy.

Here are 10 celebrities that have used surrogates to have children.

Kim Kardashian West

Kardashian West and West, who already have two kids, hired a surrogate in June to help grow their family. Although they did not use a surrogate for North, 4, or Saint, 21 months, they decided to go ahead with it for the third pregnancy because of Kardashian West’s medical condition of placenta accreta, which is when the placenta is abnormally attached to the uterine wall. The baby is due by the end of January, according to TMZ.

Amy Smart

After having fertility issues for years, Smart decided to use surrogacy and welcomed her daughter Flora in December 2016. A month after her child was born, she posted a sweet photo of the two of them to Instagram, as well as a caption revealing what she went through.

“One month ago today, Dec. 26th our amazing beautiful daughter came into this world,” Smart wrote. “Feeling so grateful to have her in my arms... after years of fertility struggles I give thanks today to our kind, loving surrogate for carrying her.”

The “8 Simple Rules” actress and her husband, “Sons of Anarchy” creator Kurt Sutter, had their daughter Esme Louise in 2007 through the use of a surrogacy mother.

“He’d never had his own biological children, so about five years into the relationship we started toying with the idea of maybe we should raise a child together,” Sagal told People in an interview about the birth of the child. “We went through the whole in vitro fertilization process and our embryos were not really strong, but we thought, ‘Let’s give it a shot and if it’s meant to be, it’s meant to be.’”

Ellen Pompeo

Pompeo was quite the keeper of secrets, as she managed to keep quiet for two months in 2014 that she had welcome her second daughter Sienna. In October of that year, she posted to Instagram to finally make the announcement, going on “Jimmy Kimmel Live!” later to give a bit more information.

“This baby was born via surrogate, so I felt an obligation to keep the surrogate’s privacy,” she said. “That was of utmost importance to me.”
