Kim Kardashian finally confirmed that she was expecting a baby boy, and now Us Weekly is claiming what we suspected from the beginning -- that Kim did gender selection to have a son!

“She only had boy embryos implanted,” a source tells the mag."Kanye and Kim are so excited to complete their family. Kanye loves Nori more than anything, but to make his world complete, he wanted a little boy, an heir." The insider added, "Kim always wanted two kids ... A girl and a boy."

Kim was doing IVF anyway, so her doctors reportedly isolated fertilized male embryos in a lab before transferring them to her uterus. The procedure starts around $15,000.

Kim is just now in the second trimester of her pregnancy, and she's been very vocal about her morning sickness. In fact, just yesterday Kim tweeted, "Wait wait wait I thought this nausea thing was supposed to be gone by now!!!! UGHHHHHH." Of course, her brother Rob caused a little bit of chaos yesterday with his replies to that tweet...

UPDATE:
Kim is denying undergoing gender selection! A spokesperson for the Kardashians told DailyMail.com on Wednesday, "The story is false."
