Rumors have been swirling that it was Kylie Jenner who birthed Kim Kardashian‘s baby girl, but the KUWTK star is finally breaking her silence and providing more information about the surrogate who helped expand her family.

“After exploring many options, Kanye and I decided to use a gestational carrier,” Kim wrote on her website. “Although I have used the term surrogate in the past, a gestational carrier is actually the technical term for a woman who carries a baby that she has no biological relationship to.” aka, not her sister. Everyone can relax now.

She went on to explain the process of using a gestational surrogate. “A traditional surrogate donates her egg, is artificially inseminated with the father’s sperm and then carries the baby to term,” she added. “Since we implanted my fertilized egg in our gestational carrier, our baby is biologically mine and Kanye’s. You can either choose someone that you know or you can go through an agency like Kanye and I did.”

She continued, “Having a gestational carrier is definitely different, but anyone who says or thinks it’s the easy way out is completely wrong. People assume it’s better because you don’t have to deal with the physical changes, pain or complications with delivery, but for me it was so hard to not carry my own child, especially after I carried North and Saint.”

Kim and Kanye welcomed baby No. 3 on Jan. 15 — and shared the exciting news. “Kanye and I are happy to announce the arrival of our healthy, beautiful baby girl,” Kim wrote. “We are incredibly grateful to our surrogate who made our dreams come true with the greatest gift one could give and to our wonderful doctors and nurses for their special care. North and Saint are especially thrilled to welcome their baby sister.”

Now that the Kylie surrogate mystery has been solved, fans can focus on what Kimye is naming their newborn daughter. Kim seemingly hinted that she was leaning toward a designer moniker in her last Instagram photo, but followers have other ideas when it comes to the name. “I would like to suggest the name Star for your new addition, as the stars are definitely shining brightly for your new baby. I’m sure she is perfect in every way,” one fan tweeted before another added, “If I was Kim Kardashian I’d name my baby Wild, but that’s just me.” Others just need to know the couple’s choice ASAP. “Okay all I need in life right now is some more sleep and for Kim Kardashian to tell the world her baby’s name,” they wrote. Same, girl, same.
